Generations of Intel Core. 5th Generation Intel Core Desktop Processors
On June 2, Intel announced ten new 14-nanometer processors for desktop and mobile PCs from the fifth-generation Intel Core family (codenamed Broadwell-C) and five new 14-nanometer processors from the Intel Xeon E3-1200 v4 family.
Of the ten new fifth-generation Intel Core processors (Broadwell-C) for desktop and mobile PCs, only two processors are desktop-oriented and have an LGA 1150 socket: these are the quad-core Intel Core i7-5775C and Core i5-5675C models. All other fifth-generation Intel Core processors are BGA-designed and are aimed at laptops. Brief characteristics of the new Broadwell-C processors are presented in the table.
| Connector | Number of cores/threads | L3 cache size, MB | TDP, W | Graphics core | ||
| Core i7-5950HQ | BGA | 4/8 | 6 | 2,9/3,7 | 47 | Iris Pro Graphics 6200 |
| Core i7-5850HQ | BGA | 4/8 | 6 | 2,7/3,6 | 47 | Iris Pro Graphics 6200 |
| Core i7-5750HQ | BGA | 4/8 | 6 | 2,5/3,4 | 47 | Iris Pro Graphics 6200 |
| Core i7-5700HQ | BGA | 4/8 | 6 | 2,7/3,5 | 47 | Intel HD Graphics 5600 |
| Core i5-5350H | BGA | 2/4 | 4 | 3,1/3,5 | 47 | Iris Pro Graphics 6200 |
| Core i7-5775R | BGA | 4/8 | 6 | 3,3/3,8 | 65 | Iris Pro Graphics 6200 |
| Core i5-5675R | BGA | 4/4 | 4 | 3,1/3,6 | 65 | Iris Pro Graphics 6200 |
| Core i5-5575R | BGA | 4/4 | 4 | 2,8/3,3 | 65 | Iris Pro Graphics 6200 |
| Core i7-5775C | LGA 1150 | 4/8 | 6 | 3,3/3,7 | 65 | Iris Pro Graphics 6200 |
| Core i5-5675C | LGA 1150 | 4/4 | 4 | 3,1/3,6 | 65 | Iris Pro Graphics 6200 |
Of the five new processors of the Intel Xeon E3-1200 v4 family, only three models (Xeon E3-1285 v4, Xeon E3-1285L v4, Xeon E3-1265L v4) have an LGA 1150 socket, and two more models are made in a BGA package and are not intended for self-installation on the motherboard. Brief characteristics of the new processors of the Intel Xeon E3-1200 v4 family are presented in the table.
| Connector | Number of cores/threads | L3 cache size, MB | Nominal/maximum frequency, GHz | TDP, W | Graphics core | |
| Xeon E3-1285 v4 | LGA 1150 | 4/8 | 6 | 3,5/3,8 | 95 | Iris Pro Graphics P6300 |
| Xeon E3-1285L v4 | LGA 1150 | 4/8 | 6 | 3,4/3,8 | 65 | Iris Pro Graphics P6300 |
| Xeon E3-1265L v4 | LGA 1150 | 4/8 | 6 | 2,3/3,3 | 35 | Iris Pro Graphics P6300 |
| Xeon E3-1278L v4 | BGA | 4/8 | 6 | 2,0/3,3 | 47 | Iris Pro Graphics P6300 |
| Xeon E3-1258L v4 | BGA | 2/4 | 6 | 1,8/3,2 | 47 | Intel HD Graphics P5700 |
Thus, out of 15 new Intel processors, only five models have an LGA 1150 socket and are aimed at desktop systems. For users, of course, the choice is small, especially considering that the Intel Xeon E3-1200 v4 family of processors is aimed at servers, and not at consumer PCs.
Moving forward, we'll focus on reviewing the new 14nm LGA 1150 processors.
So, the main features of the new fifth-generation Intel Core processors and the Intel Xeon E3-1200 v4 family of processors are the new 14-nanometer core microarchitecture, codenamed Broadwell. In principle, there is no fundamental difference between the processors of the Intel Xeon E3-1200 v4 family and the fifth generation Intel Core processors for desktop systems, so in the future we will refer to all these processors as Broadwell.
In general, it should be noted that the Broadwell microarchitecture is not just Haswell in 14-nanometer design. Rather, it is a slightly improved Haswell microarchitecture. However, Intel always does this: when switching to a new production process, changes are made to the microarchitecture itself. In the case of Broadwell, we are talking about cosmetic improvements. In particular, the volumes of internal buffers have been increased, there are changes in the execution units of the processor core (the scheme for performing multiplication and division operations on floating point numbers has been changed).
We will not consider in detail all the features of the Broadwell microarchitecture (this is a topic for a separate article), but we will once again emphasize that we are only talking about cosmetic changes to the Haswell microarchitecture, and therefore you should not expect that Broadwell processors will be more productive than Haswell processors. Of course, the transition to a new technological process has made it possible to reduce the power consumption of processors (at the same clock frequency), but no significant performance gains should be expected.
Perhaps the most significant difference between the new Broadwell and Haswell processors is the Crystalwell fourth-level cache (L4 cache). Let us clarify that such an L4 cache was present in Haswell processors, but only in top models of mobile processors, and in Haswell desktop processors with an LGA 1150 socket it was not present.
Let us recall that some top models of Haswell mobile processors implemented the Iris Pro graphics core with additional eDRAM memory (embedded DRAM), which solved the problem of insufficient memory bandwidth used for the GPU. eDRAM memory was a separate crystal, which was located on the same substrate with the processor crystal. This crystal was codenamed Crystalwell.
The eDRAM memory had a size of 128 MB and was manufactured using a 22-nanometer process technology. But the most important thing is that this eDRAM memory was used not only for the needs of the GPU, but also for the computing cores of the processor itself. That is, in fact, Crystalwell was an L4 cache shared between the GPU and the processor cores.
All new Broadwell processors also include a separate 128 MB eDRAM memory die, which acts as an L4 cache and can be used by the graphics core and the processor's compute cores. Moreover, we note that the eDRAM memory in 14-nanometer Broadwell processors is exactly the same as in top-end Haswell mobile processors, that is, it is manufactured using a 22-nanometer technical process.
The next feature of the new Broadwell processors is the new graphics core, codenamed Broadwell GT3e. In the version of processors for desktop and mobile PCs (Intel Core i5/i7) it is Iris Pro Graphics 6200, and in processors of the Intel Xeon E3-1200 v4 family it is Iris Pro Graphics P6300 (with the exception of the Xeon E3-1258L v4 model). We will not delve into the specifics of the Broadwell GT3e graphics core architecture (this is a topic for a separate article) and will only briefly consider its main features.
Let us recall that the Iris Pro graphics core was previously present only in Haswell mobile processors (Iris Pro Graphics 5100 and 5200). Moreover, the Iris Pro Graphics 5100 and 5200 graphics cores have 40 execution units (EU). The new graphics cores Iris Pro Graphics 6200 and Iris Pro Graphics P6300 are already equipped with 48 EUs, and the EU organization system has also changed. Each individual GPU unit contains 8 EUs, and the graphics module combines three graphics units. That is, one graphics module contains 24 EU, and the Iris Pro Graphics 6200 or Iris Pro Graphics P6300 graphics processor itself combines two modules, that is, a total of 48 EU.
As for the difference between the graphics cores of Iris Pro Graphics 6200 and Iris Pro Graphics P6300, at the hardware level they are the same (Broadwell GT3e), but their drivers are different. In the Iris Pro Graphics P6300 version, the drivers are optimized for tasks specific to servers and graphics stations.
Before moving on to a detailed review of the Broadwell testing results, we’ll tell you about a few more features of the new processors.
First of all, the new Broadwell processors (including the Xeon E3-1200 v4) are compatible with motherboards based on Intel 9-series chipsets. We can't say that every board based on the Intel 9-series chipset will support these new Broadwell processors, but most boards do support them. True, for this you will have to update the BIOS on the board, and the BIOS must support new processors. For example, for testing we used the ASRock Z97 OC Formula board and without updating the BIOS, the system only worked with a discrete video card, and image output through the graphics core of Broadwell processors was impossible.
The next feature of the new Broadwell processors is that the Core i7-5775C and Core i5-5675C models have an unlocked multiplier, that is, they are focused on overclocking. In the Haswell family of processors, such processors with unlocked multipliers made up the K-series, and in the Broadwell family, the letter “C” is used instead of the letter “K”. But the Xeon E3-1200 v4 processors do not support overclocking (it is impossible to increase the multiplication factor for them).
Now let's take a closer look at the processors that came to us for testing. These are models , and . In fact, of the five new models with the LGA 1150 socket, the only thing missing is the Xeon E3-1285L v4 processor, which differs from the Xeon E3-1285 v4 only in lower power consumption (65 W instead of 95 W) and the fact that its nominal core clock speed slightly lower (3.4 GHz instead of 3.5 GHz). Additionally, for comparison, we also added the Intel Core i7-4790K, which is the top processor in the Haswell family.
The characteristics of all tested processors are presented in the table:

And now, after our express review of the new Broadwell processors, let's move on directly to testing the new products.
Test bench
To test processors, we used a bench with the following configuration:
Testing methodology
Processor testing was carried out using our scripted benchmarks, and. More precisely, we took the methodology for testing workstations as a basis, but expanded it by adding tests from the iXBT Application Benchmark 2015 package and iXBT Game Benchmark 2015 game tests.
Thus, the following applications and benchmarks were used to test processors:
- MediaCoder x64 0.8.33.5680
- SVPmark 3.0
- Adobe Premiere Pro CC 2014.1 (Build 8.1.0)
- Adobe After Effects CC 2014.1.1 (Version 13.1.1.3)
- Photodex ProShow Producer 6.0.3410
- Adobe Photoshop CC 2014.2.1
- ACDSee Pro 8
- Adobe Illustrator CC 2014.1.1
- Adobe Audition CC 2014.2
- Abbyy FineReader 12
- WinRAR 5.11
- Dassault SolidWorks 2014 SP3 (Flow Simulation package)
- SPECapc for 3ds max 2015
- SPECapc for Maya 2012
- POV-Ray 3.7
- Maxon Cinebench R15
- SPECviewperf v.12.0.2
- SPECwpc 1.2
In addition, games and gaming benchmarks from the iXBT Game Benchmark 2015 package were used for testing. Testing in games was carried out at a resolution of 1920x1080.
Additionally, we measured the power consumption of processors in idle mode and under stress. For this purpose, a specialized software and hardware complex was used, which was connected to the gap in the power supply circuits of the system board, that is, between the power supply and the system board.
To create CPU stress, we used the AIDA64 utility (Stress FPU and Stress GPU tests).
Test results
Processor power consumption
So, let's start with the results of testing processors for energy consumption. The test results are presented in the diagram.
The most voracious in terms of energy consumption, as one might expect, turned out to be the Intel Core i7-4790K processor with a declared TDP of 88 W. Its real power consumption in stress load mode was 119 W. At the same time, the temperature of the processor cores was 95°C and throttling was observed.
The next most power consuming processor was the Intel Core i7-5775C processor with a stated TDP of 65 W. For this processor, power consumption in stress mode was 72.5 W. The temperature of the processor cores reached 90 °C, but throttling was not observed.
The third place in terms of energy consumption was taken by the Intel Xeon E3-1285 v4 processor with a TDP of 95 W. Its power consumption in stress mode was 71 W, and the temperature of the processor cores was 78 °C
And the most economical in terms of energy consumption was the Intel Xeon E3-1265L v4 processor with a TDP of 35 W. In stress load mode, the power consumption of this processor did not exceed 39 W, and the temperature of the processor cores was only 56 °C.
Well, if we focus on the power consumption of processors, we must state that Broadwell has significantly lower power consumption compared to Haswell.
Tests from the iXBT Application Benchmark 2015 package
Let's start with the tests included in the iXBT Application Benchmark 2015. Note that we calculated the integral performance result as the geometric mean of the results in logical groups of tests (video conversion and video processing, video content creation, etc.). To calculate results in logical groups of tests, the same reference system was used as in the iXBT Application Benchmark 2015.
Full test results are shown in the table. In addition, we present the test results for logical groups of tests on diagrams in a normalized form. The result of the Core i7-4790K processor is taken as the reference.
| Logical test group | Xeon E3-1285 v4 | Xeon E3-1265L v4 | Core i5-5675C | Core i7-5775C | Core i7-4790K |

| Vector graphics, points | 150,6 | 130,7 | 140,6 | 147,2 | 177,7 |
| Adobe Illustrator CC 2014.1.1, seconds | 341,9 | 394,0 | 366,3 | 349,9 | 289,8 |
| Audio processing, points | 231,3 | 203,7 | 202,3 | 228,2 | 260,9 |
| Adobe Audition CC 2014.2, seconds | 452,6 | 514,0 | 517,6 | 458,8 | 401,3 |
| Text recognition, points | 302,4 | 263,6 | 205,8 | 269,9 | 310,6 |
| Abbyy FineReader 12, seconds | 181,4 | 208,1 | 266,6 | 203,3 | 176,6 |

| WinRAR 5.11 unzipping, seconds | 7,3 | 8,1 | 8,29 | 7,4 | 7,0 |
| Integral performance result, points | 259,1 | 226,8 | 212,8 | 237,6 | 262,7 |
So, as can be seen from the testing results, in terms of integrated performance, the Intel Xeon E3-1285 v4 processor is practically no different from the Intel Core i7-4790K processor. However, this is an integral result based on the totality of all applications used in the benchmark.
However, there are a number of applications that benefit from the Intel Xeon E3-1285 v4 processor. These are applications such as MediaCoder x64 0.8.33.5680 and SVPmark 3.0 (video conversion and video processing), Adobe Premiere Pro CC 2014.1 and Adobe After Effects CC 2014.1.1 (video content creation), Adobe Photoshop CC 2014.2.1 and ACDSee Pro 8 (digital processing photographs). In these applications, the higher clock speed of the Intel Core i7-4790K processor does not give it an advantage over the Intel Xeon E3-1285 v4 processor.
But in applications such as Adobe Illustrator CC 2014.1.1 (vector graphics), Adobe Audition CC 2014.2 (audio processing), Abbyy FineReader 12 (text recognition), the advantage is on the side of the higher-frequency Intel Xeon E3-1285 v4 processor. It is interesting to note that tests based on the Adobe Illustrator CC 2014.1.1 and Adobe Audition CC 2014.2 applications load the processor cores to a lesser extent (compared to other applications).
And of course, there are tests in which the Intel Xeon E3-1285 v4 and Intel Core i7-4790K processors demonstrate the same performance. For example, this is a test based on the WinRAR 5.11 application.
In general, it should be noted that the Intel Core i7-4790K processor demonstrates higher performance (compared to the Intel Xeon E3-1285 v4 processor) precisely in those applications in which not all processor cores are used or the cores are not fully loaded. At the same time, in tests where all processor cores are loaded at 100%, the leadership is on the side of the Intel Xeon E3-1285 v4 processor.
Calculations using Dassault SolidWorks 2014 SP3 (Flow Simulation)
We presented the test based on the Dassault SolidWorks 2014 SP3 application with the additional Flow Simulation package separately, since this test does not use a reference system, as in the tests of the iXBT Application Benchmark 2015.
Let us remind you that in this test we are talking about hydro/aerodynamic and thermal calculations. A total of six different models are calculated, and the results of each subtest are the calculation time in seconds.
Detailed test results are presented in the table.
| Test | Xeon E3-1285 v4 | Xeon E3-1265L v4 | Core i5-5675C | Core i7-5775C | Core i7-4790K |
| conjugate heat transfer, seconds | 353.7 | 402.0 | 382.3 | 328.7 | 415.7 |
| textile machine, seconds | 399.3 | 449.3 | 441.0 | 415.0 | 510.0 |
| rotating impeller, seconds | 247.0 | 278.7 | 271.3 | 246.3 | 318.7 |
| CPU cooler, seconds | 710.3 | 795.3 | 784.7 | 678.7 | 814.3 |
| halogen floodlight, seconds | 322.3 | 373.3 | 352.7 | 331.3 | 366.3 |
| electronic components, seconds | 510.0 | 583.7 | 559.3 | 448.7 | 602.0 |
| Total calculation time, seconds | 2542,7 | 2882,3 | 2791,3 | 2448,7 | 3027,0 |
In addition, we also present the normalized result of the calculation speed (the reciprocal of the total calculation time). The result of the Core i7-4790K processor is taken as the reference.
As can be seen from the testing results, in these specific calculations the leadership is on the side of Broadwell processors. All four Broadwell processors demonstrate faster calculation speeds compared to the Core i7-4790K processor. Apparently, these specific calculations are affected by the improvements in the execution units that were implemented in the Broadwell microarchitecture.
SPECapc for 3ds max 2015
Next, let's look at the results of the SPECapc for 3ds max 2015 test for the Autodesk 3ds max 2015 SP1 application. The detailed results of this test are presented in the table, and the normalized results for the CPU Composite Score and GPU Composite Score are presented in the charts. The result of the Core i7-4790K processor is taken as the reference.
| Test | Xeon E3-1285 v4 | Xeon E3-1265L v4 | Core i5-5675C | Core i7-5775C | Core i7-4790K |
| CPU Composite Score | 4,52 | 3,97 | 4,09 | 4,51 | 4,54 |
| GPU Composite Score | 2,36 | 2,16 | 2,35 | 2,37 | 1,39 |
| Large Model Composite Score | 1,75 | 1,59 | 1,68 | 1,73 | 1,21 |
| Large Model CPU | 2,62 | 2,32 | 2,50 | 2,56 | 2,79 |
| Large Model GPU | 1,17 | 1,08 | 1,13 | 1,17 | 0,52 |
| Interactive Graphics | 2,45 | 2,22 | 2,49 | 2,46 | 1,61 |
| Advanced Visual Styles | 2,29 | 2,08 | 2,23 | 2,25 | 1,19 |
| Modeling | 1,96 | 1,80 | 1,94 | 1,98 | 1,12 |
| CPU Computing | 3,38 | 3,04 | 3,15 | 3,37 | 3,35 |
| CPU Rendering | 5,99 | 5,18 | 5,29 | 6,01 | 5,99 |
| GPU Rendering | 3,13 | 2,86 | 3,07 | 3,16 | 1,74 |
Broadwell processors take the lead in the SPECapc 3ds for max 2015 test. Moreover, if in subtests depending on CPU performance (CPU Composite Score), Core i7-4790K and Xeon E3-1285 v4 processors demonstrate equal performance, then in subtests depending on graphics core performance (GPU Composite Score), all Broadwell processors significantly ahead of the Core i7-4790K processor.
SPECapc for Maya 2012
Now let's look at the result of another 3D modeling test - SPECapc for Maya 2012. Let us recall that this benchmark was run in conjunction with the Autodesk Maya 2015 package.
The results of this test are presented in a table, and the normalized results are presented in diagrams. The result of the Core i7-4790K processor is taken as the reference.
| Test | Xeon E3-1285 v4 | Xeon E3-1265L v4 | Core i5-5675C | Core i7-5775C | Core i7-4790K |
| GFX Score | 1,96 | 1,75 | 1,87 | 1,91 | 1,67 |
| CPU Score | 5,47 | 4,79 | 4,76 | 5,41 | 5,35 |
In this test, the Xeon E3-1285 v4 processor demonstrates slightly higher performance compared to the Core i7-4790K processor, however, the difference is not as significant as in SPECapc 3ds for max 2015.
POV-Ray 3.7
In the POV-Ray 3.7 test (3D model rendering), the leader is the Core i7-4790K processor. In this case, a higher clock speed (with an equal number of cores) gives an advantage to the processor.
| Test | Xeon E3-1285 v4 | Xeon E3-1265L v4 | Core i5-5675C | Core i7-5775C | Core i7-4790K |
| Render average, PPS | 1568,18 | 1348,81 | 1396,3 | 1560.6 | 1754,48 |
Cinebench R15
In the Cinebench R15 benchmark, the result was mixed. In the OpenGL test, all Broadwell processors significantly outperform the Core i7-4790K processor, which is natural since they integrate a more powerful graphics core. But in the processor test, on the contrary, the Core i7-4790K processor turns out to be more productive.
| Test | Xeon E3-1285 v4 | Xeon E3-1265L v4 | Core i5-5675C | Core i7-5775C | Core i7-4790K |
| OpenGL, fps | 71,88 | 66,4 | 72,57 | 73 | 33,5 |
| CPU, cb | 774 | 667 | 572 | 771 | 850 |
SPECviewperf v.12.0.2
In the tests of the SPECviewperf v.12.0.2 package, the results are determined primarily by the performance of the processor's graphics core and, in addition, by the optimization of the video driver for certain applications. Therefore, in these tests the Core i7-4790K processor lags significantly behind the Broadwell processors.
The test results are presented in the table, as well as in normalized form in diagrams. The result of the Core i7-4790K processor is taken as the reference.

This is not to say that everything in this test is clear. In some scenarios (Media and Entertainment, Product Development, Life Sciences), Broadwell processors demonstrate better results. There are scenarios (Financial Services, Energy, General Operation) where the advantage is on the side of the Core i7-4790K processor or the results are approximately the same.
Game tests
And finally, let's look at the results of testing processors in gaming tests. Let us remind you that for testing we used the following games and gaming benchmarks:
- Aliens vs Predator
- World of Tanks 0.9.5
- Grid 2
- Metro: LL Redux
- Metro: 2033 Redux
- Hitman: Absolution
- Thief
- Tomb Raider
- Sleeping Dogs
- Sniper Elite V2
Testing was carried out at a screen resolution of 1920x1080 and in two setting modes: maximum and minimum quality. Test results are presented in diagrams. In this case, the results are not standardized.
In gaming tests, the results are as follows: all Broadwell processors show very close results, which is natural since they use the same Broadwell GT3e graphics core. And most importantly, with minimum quality settings, Broadwell processors allow you to comfortably play (at FPS over 40) most games (at a resolution of 1920x1080).
On the other hand, if the system uses a discrete graphics card, then there is simply no point in the new Broadwell processors. That is, there is no point in changing Haswell to Broadwell. And the price of Broadwells is not so attractive. For example, Intel Core i7-5775C is more expensive than Intel Core i7-4790K.
However, Intel does not seem to be betting on Broadwell desktop processors. The range of models is extremely modest, and Skylake processors are on the way, so it’s unlikely that Intel Core i7-5775C and Core i5-5675C processors will be in particular demand.
Server processors of the Xeon E3-1200 v4 family are a separate market segment. For most ordinary home users, such processors are of no interest, but in the corporate sector of the market these processors may be in demand.
Thanks to the improvement of the technical process, it was possible to achieve a significant increase in productivity, which will amount to more than 15% according to the SysMark test. Thus, this year the performance of Core i7 processors will increase more than last year. This is shown in the slide from the presentation at the top, titled "Advancing Moore's Law at 14nm."
A new generation of processors on the improved 14 nm platform is scheduled for release in the second half of 2017. They will be designated as the Core i7/i5/i3-8000 family and will replace the existing 7th generation family.
At the investor presentation, Intel said nothing about plans to release the Cannonlake (formerly Skymont) family of microprocessors based on the 10nm process technology. They are supposed to be released at the end of 2017, and a working sample of Cannonlake at 10 nm was recently shown at CES. It was the Cannonlake family that was previously positioned as the 8th generation of processor architecture, which will replace Skylake as part of the “tick-tock” strategy. Now another family has appeared that has nothing to do with Cannonlake. Perhaps this is an attempt to sell an old product in new packaging.
Cancel the tick-tock strategy
Intel has consistently pursued a tick-tock strategy since 2006. Since then, every two years it has released processors using a new process technology, significantly increasing the number of transistors on the chip. Each transition to a new technical process was designated as a “tick”, and the subsequent improvement of the microarchitecture with the same technical process was designated as “tock”. The semiconductor industry giant worked like clockwork for ten years, releasing new architectures without failure.It appears that in 2016 Intel's clock shortened slightly at 14nm and the company announced .
In principle, there is nothing wrong with this. Again, this year's chip performance growth (more than 15%) will be even greater than last year's (15%), Intel said. Maybe it’s really better to squeeze out all the reserves from the existing technical process, optimizing it, and only then move on. We can't criticize Intel for moving away from the strategy it voluntarily set for itself.
One way or another, but now the “tick-tock” strategy has been modified into a different form.
Instead of a measured metronome, a new procedure has now been implemented with a greater emphasis on optimization. Perhaps new architecture will not be released every two years, as it was before.
Why doesn't Intel force the transition to 10 nm? It doesn't need to do this because it believes that it is already far behind its competitors in the semiconductor industry (Samsung, TSMC, etc.) in its technological superiority. The company estimates this gap to be approximately three years.
This reserve allows you to feel quite confident.
New plant for 7 nm
The bright future of Moore's Law should be ensured by the new Intel Fab 42 plant, which can support production using the 7 nm process technology.
Construction and equipment will take another three to four years and require significant investment. The Chandler, Arizona plant will reduce local unemployment by approximately 3,000 people (+ another 10,000 jobs will be added indirectly).
Construction of the Chandler plant began in 2011. It is set to become the most advanced and innovative semiconductor facility in the world. The building itself was completed in 2013, but instead of installing equipment at 14 nm in early 2014, Intel decided to delay the launch of the pipeline. At the moment, the plant is ready: air conditioning, heating and other systems - everything is functioning, all that remains is to install and adjust the equipment. Intel does not plan to use this factory for production at the 10 nm process technology, so in a few years it will likely master production at the next 7 nm standard.
According to Intel, the equipment will cost approximately $7 billion. This is the cost of a modern industrial enterprise. It is not yet known what specific equipment will be needed. Perhaps Intel will start using deep ultraviolet (EUV) photolithography there.
At the dawn of the 2000s, Intel hoped that by 2005 processor frequencies would increase to 10 GHz, and they would operate at voltages below volts. As we know, this did not happen. About ten years ago, Dennard's scaling law, which stated that by reducing the size of transistors, the voltage applied to the gate could be reduced and the switching speed increased, stopped working. Since then, rarely has a processor received a standard operating frequency above 4 GHz, but there have been more cores, the north bridge has been moved to the chip from the motherboard, and other optimizations and accelerations have appeared. Now Moore's law, an empirical observation that indicates a constant increase in the number of transistors on a chip due to a decrease in their size, is also slowing down.
We reviewed the “top” worst gaming video cards. Now, after the release of Coffee Lake, we can make a list of the worst processors, since nothing particularly important is observed on the CPU market until the end of the year. Of course, I will only consider the relevance of buying such processors now: if you already own one of the “stones” below, then you clearly had your reasons for buying it.
Intel Core i7-7740X and Core-i5 7640X (Kaby Lake-X) - welcome to 2010
It's mid-2017. AMD introduces the first honest eight-core desktop processor - Ryzen 7. Intel introduces new processors for its high-performance platform, now called Skylake-X and Kaby Lake-X. This may include solutions with 16 or even 18 cores, and the simplest representatives have... wait, 4 cores?! Hmm, how do they then differ from the simple i5-7600K and i7-7700K? The frequencies are the same, the number of memory channels and PCIe lanes is the same, as are the instruction sets. Except that the X-line does not have a built-in video core, but this is more a minus than a plus. Taking into account the fact that these processors are more expensive than their non-X counterparts, and motherboards based on the X299 chipset are expensive, there is absolutely no point in buying these “stones”, and it is difficult to explain the point of their release - well, unless Intel has a lot of unnecessary 4-core ones lying around crystals.
AMD FX - goodbye gaming bulldozer 
The FX line, which was the top line before the release of Ryzen for almost seven years, can now safely retire. To tell the truth, even at the time of its release it was not top-end: and although the programs showed that the FX-8000 line had as many as 8 cores, in reality these were 4 APUs, and according to tests, the top FX was at the level of the best i5s, while the i7s were are not achievable - that is why Intel did not “itch” then, continuing to release new processors with a 5% increase in performance per generation. Before the release of 4-thread Pentiums at the beginning of this year, it made sense to buy the FX-4000 line - they were extremely cheap, but at the same time they made it possible to create a basic gaming system with video cards of the GTX 750 Ti and even GTX 950 level. But, alas, the new Pentiums turned out to be so good for leaving junior FX without work. Well, AMD “finished off” the older representatives, FX-8000, themselves by releasing the younger Ryzen 3 at the same price and with higher performance and lower heat generation. So the FX line, which was once a good choice for building mid-budget gaming builds, is now finally time to retire.
But still, these processors can be taken in one case - for the sake of an upgrade: for example, if you have an FX-4000 line, then now is the time to upgrade to the FX-8000 - you will get double the performance for quite little money. Considering that the 8000 line pulls out video cards of the level of GTX 1060 or RX 580, you will be able to play comfortably for another couple of years.
Most of the representatives of the Skylake and Kaby Lake lines - Intel is strangling the “old stuff” 
Rumors that Intel should release desktop processors with a large number of cores have been floating around for a long time, and now it has happened, and since October 5th the Internet has been flooded with their tests. And, alas, they clearly show that the previous lines no longer have a place in the Sun: why buy an 8-thread processor for 19 thousand rubles, if the youngest 12-thread one costs only 20.5 thousand, and even when overclocked, the previous generation is at least 20% worse? It’s the same with the i5, and even more so with the i3 of the 6th and 7th generations - the latter were already meaningless processors on the market after the appearance of the new Pentiums, but now, after the release of the 4-core i3 of the 8th generation, i3 Skylake and Kaby Lake can definitely be written off as scrap.
By the way, now the line of processors from Intel looks quite logical: the very, very low-level are 2-core Celerons: they are quite enough for comfortable browsing the Internet and watching movies, and even simple games like Dota, WoT and CS:GO. The next step is Pentium, which still has the same 2 cores, but already 4 threads, and slightly higher frequencies - on their basis you can already assemble a low-middle level gaming system. Core i3, which is now 4-core, goes one step higher, allowing you to create a middle-level assembly. Well, for the top, there are 6-core i5 and i7 - for those who want to get the best gaming solution on the market.
But, however, there is one reason why “old” processors are worth taking, and it is still the same - an upgrade. For example, a couple of years ago you got yourself a junior i5-6400. And now there is a good opportunity to upgrade it to the i7-7700K and get a twofold increase in performance, and not too expensive (especially if you sell the i5).
Haswell-E and Broadwell-E line - oldies at top prices 
Let's see how much the 8-core processor of the new Skylake-X line costs - Intel Core i7-7820X. In Moscow retail, the price tag for it is about 40 thousand rubles. Expensive, you say? Well, here for this price we get 8 cores on a new architecture with a frequency of 4 GHz - quite good for a high-performance PC. Still expensive? Hmm, okay, let's look at the previous generation processors - they should be cheaper, right? So, the analogue from Broadwell-E is the i7-6900X: also 8 cores, but on the previous architecture, and the frequency is about 3.5 GHz. And the price... 70 thousand rubles?! Where? Why? Let's look for the advantages of the old processor. And yet, yes, we find one - it’s solder under the lid, which allows it to be overclocked better than the Skylake-X representatives with “mayonnaise” instead of solder. But even if you are very lucky and overclock the i7-6900X so that it is at the level of the i7-7820X, this will not eliminate the almost twofold difference in price.
As a result, Intel killed two old lines at once this year - Broadwell-E and Kaby Lake, and the latter is not even a year old. That's what it is, a monopoly...
AMD Ryzen with X - the company is stepping on the same rake 
Those who remember AMD FX processors know that there was no point in overpaying for the older processors in the line - all processors could be overclocked, so the younger “stone” turned into the older one with one easy wave of the hand. And for some reason AMD continued this in Ryzen, and here it reaches the point of absurdity: for example, the junior Ryzen 7 1700 costs about 20 thousand rubles. The older 7 1800X already costs 30 thousand - one and a half times more expensive. And their overclocking potential is the same - about 4 GHz. Is it worth paying extra for the 1800X? I think the answer is obvious. And so in all Ryzen lines - 3, 5 and 7 - it makes sense to take a junior processor, without the X index, and overclock it to the level of the older one.
AMD Bristol Ridge - for those who don't have money for Ryzen 
AMD, with the same tenacity, continues to develop its APUs - two-in-one systems, where an average CPU includes full-fledged graphics from AMD, only with a lower number of computing units and frequency than in full-fledged video cards. In principle, it’s a pretty good solution for those who need a simple home PC - the processor performance is enough to make the OS, browser and movies work quickly, and the GPU will even allow you to play new games, albeit in HD resolution and with low graphics settings. Well, and most importantly, the new APUs are compatible with AM4, that is, in the future, no one is stopping you from replacing such a processor with some kind of Ryzen 7, which is good for those who are building a PC in stages.
But, on the other hand, yes, this is a budget solution, but why is it based on the Excavator architecture, which is 7 years old at lunchtime, and even at 28 nm?! Was it really so difficult to make these “stones” on Zen, which would also allow the heat dissipation to be reduced from 65 to 30 W, acceptable for such a system? In general, APUs are strange - on the one hand they are new, on the other they are ancient. But, in principle, they can find their buyers.
But we started talking about desktops, it’s time to move on to mobile processors, because they are also full of strange “features”.
Intel Celeron N3050 and N3350 - worse than Atom for the same money
For some reason, branded laptop manufacturers have one trick - we install Celeron and Pentium in netbooks/laptops, and Atom in tablets. It would seem that everything is correct, Celeron should be better than Atom, but no - Intel thinks differently: the architecture of these processors is similar, but Atom has 4 computing cores, while Celeron has only 2. Taking into account the fact that we are considering the lowest -level (10-15 thousand rubles), a couple of cores will not be superfluous here, and while laptops on Celeron may well start to freeze with 3-4 tabs in Chrome, Atom is quite capable of simultaneous surfing and watching a PiP movie. And taking into account the fact that for $150 you can simply remain silent about the quality of branded netbooks, it makes sense to take a solution from any Digma or iRu, but with Atom, and get seriously better performance for the same money.
Intel Core i3-6006U and Pentium 4405U - i3 is worse than Pentium 
After Atom, which is better than Celeron, it would seem much worse. However, they knocked on the bottom - the i3-6006U, quite widespread in the 18-25 thousand rubles segment... worse than its brother in the same segment, but from the Pentium camp! Let's take a closer look at these processors: both have 2 cores and 4 threads, the same set of instructions, however, the Pentium has a 100 MHz higher frequency, but at the same time the integrated graphics are twice as bad: HD 510 versus HD 520 for i3. It would seem that 100 MHz frequency (+5%) will definitely not outweigh twice the worst graphics, but there are two nuances here:
- If the laptop has discrete graphics (and often it does - this is the Nvidia GT 920M), then it makes no difference at all to the integrated graphics - it’s the “discrete” graphics that will work in games, so here a slightly higher-frequency Pentium is better.
- If a person has chosen a laptop without discrete graphics, it means that he does not need games, and both integrated video cards cope equally well with GUI rendering and playback, including 1080p60, which means, again, there is no point in taking an i3.
Mobile processors from AMD - Intel still won the war
The fact that AMD did not really update its mobile processors for a couple of years, and Intel even increased the number of cores to 4 in low-voltage solutions, led to the fact that it simply does not make sense to buy laptops with AMD processors - analogues on Intel processors will be more productive, and more autonomous. Yes, the “reds” do not want to lose the mobile market, and are actively making mobile Ryzen, but so far the only thing that is on the Internet is a couple of tests, where AMD processors again do not perform in the best light. Of course, when they come out, everything may change, but for now Intel reigns in the mobile segment. You can read more about this.
What's the result? But in the end, the same confusion and vacillation as with video cards - there are excellent solutions, there are good ones, and there are those that, when you see them, you think - what was the manufacturer guided by when releasing this?! But what’s good is that the processor market has been seriously moving lately, and mainly thanks to AMD: Intel rolled out 6-core desktop processors in response to 8-core Ryzen processors, and in the mobile segment the number of cores in the same lines has also increased. So those who wanted to upgrade or build a new PC - IMHO, it's time to get started.
Choosing a processor is quite a serious task, which should be approached only after you have thoroughly familiarized yourself with all the nuances and characteristics. Much can be learned from the name of the processor, its markings, which contain information about the main characteristics of this model. You can read what these characteristics mean in this article, and in this article we will talk about how to decipher the processor markings.
Intel processor markings
- Intel processor series
- I7 – top processors that support all Intel technologies, have 4 cores, and are equipped with an 8 MB L3 cache.
- I5 – mid-price segment processors, can have from 2 to 4 cores. Equipped with L3 cache memory with a capacity of 3 to 6 MB. There is no support for Trusted Execution, Hyper-Threading and Virtualization Technology.
- I3 is a budget series of processors that has 2 cores and a 3 MB L3 cache.
- Indicates the generation of the Core i-x series of processors. SandyBridje is marked with the number 2, IvyBridge is marked with the number 3.
- Indicates position in the series. The higher the number, the faster the processor runs. Depends on the clock frequency.
- Processor version
- K – this processor has an unlocked multiplier, which means it can be overclocked.
- M – processor used in mobile devices (smartphone, tablet).
- P – processor without automatic overclocking.
- S – such processors have power consumption reduced to 65 W.
- T – these processors have reduced power consumption to 45/35 W.

Intel processor markings
Marking of intel processors and determination of the generation of processors of the intel core I3/I5/i7 series.
Marking of old processors for socket Lga 775.
Celeron is a modification of budget processors. (Still released on new platforms).
The number is a model range; the higher the number, the better the processor.
In new processors, everything is very unclear about the model number, so it is better to look for information about these processors on the intel page.
Processors labeled Core 2 Duo
Core 2 Duo E8400 and Core 2 Duo X6800
Core 2 duo modification of the processor.
E8400 model number, the higher the better. (If compared with one line of processors).
But don't forget about the characteristics of the processor itself.
The letter X on some processors means that the processor is Extreme Edition. With an unlocked multiplier.
Processors labeled Pentium Dual-Core (released on new platforms) are also a modification of the processor better than Celeron.
Example E5700 is a model range; the higher the number, the more powerful the processor.
In new processors, how they are marked is unclear; you cannot determine on which core it was made; we look for information about these processors on the intel page.
Modifier Core 2 Quad processors are the first of four core processors.
Q6600 letter Q means that the processor is 4-core (quad).
Some processors are designated QX9650, the letter X indicates that the processor is Extreme Edition. (unlocked multiplier)
Low power consumption are designated by the letter suffix S
In terms of numbers, as everywhere else, the higher the better.
also see the table Characteristics of INTEL processors (LGA 775)
We got to the latest intel processors codenamed core I3, core I5, core I7.
Core i3, i5, i7 of the first generation did not have a generation number, so they have three-digit designations.
Core I3 550, Core I5 670, Core I7 920.
Intel® Core™ processor numbers 2nd, 3rd, 4th, 5th, 6th use a four-digit value.
You can find out the Intel Core generation by the first digit of the four-digit sequence indicates the generation of the processor, the next three digits are the processor code or model number and a letter suffix depending on the processor.
Using the first digit we determine the generation of the processor; if there are only 3 digits, this means it is the first generation.
The model range or processor code means that the higher the numbers, the more powerful the processor; also, do not forget about suffixes.
All suffixes related to energy consumption mean frequencies lower than usual.
An example is the i7 4770 (3.50 GHz) and i7 4770T (2.50 GHz). Hence the conclusion is that the i7 4770 is simply better than the i7 4770T in terms of performance.
Existing suffixes
| Desktop | For Mobile Devices |
| K-With overclock protection removed (multiplier unlocked) | M-for mobile PCs |
| S-Optimized Performance | QM-Quad core processors for mobile PCs. |
| T-Optimized energy consumption | U- Ultra-low power consumption. |
| R-Desktop processors in BGA1364 package (for mobile devices) with high-performance graphics solution. | Y - extreme low power consumption. |
| C-Unlocked LGA 1150 desktop processors with high-performance graphics (4th and 5th generation). | HQ-High-performance graphics solution. |
| H-High Performance Graphics Solution | |
| HK-High performance graphics, unlocked multiplier. | |
| MX-Series extreme edition for mobile PCs. |

How to choose the best processor
At a certain point, every computer user faces the problem of upgrading the system or buying a new machine. As a rule, the financial resource for this is limited, but you need to assemble a productive configuration.
Each has its own requirements for the system, which means that each needs its own processor (CPU) corresponding to the level of tasks performed. Based on CPU performance, CPUs are usually divided into categories: beginner, intermediate, or basic, and advanced.
- Processor selection criteria
- Intel processor
- Processor prices
Manufacturer. There are only two of them - Intel and AMD, and each has models worthy of attention. The main strength of the first is low power consumption combined with high performance, the second is built-in powerful graphics cards, and stones with more than four cores.
Type of processor socket, otherwise known as socket. It partly determines the generation of the processor and the model of motherboard with which it is compatible. When choosing, you need to pay attention to this, and not take an outdated platform that has no prospect of modernization (for example, Intel 1155, and AMDFM1).
Number of cores. A characteristic that directly affects performance, but is in demand only in resource-intensive applications and 3D games. Office tasks and watching movies do not use all the computing power.
Clock frequency. The performance characteristic, measured in gigahertz, reflects the number of simple calculations per second. The higher the frequency, the higher the performance.
Cache memory. Participates in the exchange of data between the processor and RAM. Has several levels. The larger its size and the greater the number of such levels, the more productive the CPU.
Data bus frequency. Characterizes the speed of information exchange between the processor and the computer system bus. System performance directly depends on its frequency.
Built-in graphics. Almost all new CPUs come with an integrated video card. Its main purpose is to be an alternative to inexpensive discrete graphics, although some models are capable of showing decent performance in not the most complex games (see Which video card is best for gaming). AMD processors have a relatively powerful integrated graphics core.
Intel processor
Processor markings consist of numbers. The first determines the generation, for example, Corei3 3245 belongs to the third. Sometimes there are letters after the numbers that mean:
- K – accelerates;
- S and T – the core has reduced heat generation and power consumption. These features come at the cost of reduced performance;
- R – speaks of a powerful built-in video core.
You should also outline the differences between the Corei3, i5 and i7 lines. The first ones have two cores, but have Hyper-Treading, i.e. process four data streams and are visible in the system as quad-core. The i5 series has four cores and TurboBoost technology, which increases the frequency of the CPU, giving an additional boost in performance. The seventh series has all the features of the previous lines.
Hyper-Treading means that the processor physically has one core, but due to the technology, the second core (logical) is created virtually, i.e. the number of physical ones is multiplied by two.
Processor prices
The best budget processors are the Celeron G1620 and PentiumG3450. Their socket is on the aging 1155 platform, but the price/performance ratio makes it worth the purchase. Both have dual cores, L3 cache, and extremely low power consumption.
Perfect for office programs, watching good quality videos and listening to music (see Why there is no sound on a computer or laptop). When working together with a discrete video card, most games can be played, although not at high graphics settings.
An alternative from competitors - A4-7300, A6-7400K on the current FM2+ platform is slightly slower in terms of characteristics, there is no Level III cache, but they are cheaper and have a strong integrated video card.
The middle level is characterized by a large number of options, and the purpose of using computers in this price niche varies from office tasks and multimedia centers to productive gaming machines.
The best inexpensive solution for this is the new sixth-generation Core i3-6300 chip, operating at a 3.7 GHz clock frequency.
Like all members of this family, it has two cores, but uses four data streams and Hyper Threading technology. If the buyer, due to the fact that the new product is still rare on the shelves, does not have the opportunity to purchase it, an excellent alternative would be the 4th generation stone Corei3-4160, which has similar characteristics, but with an older, although still relevant, socket1150.
The more powerful Corei5-4590 also belongs to the middle level. An alternative from AMD would be the AthlonX4 860K, A8-7600, FX-8320, which combine lower cost with excellent performance.
Powerful gaming processors for a computer based on Intel Corei7-4790K or Corei7-6700K will show the best performance in games with maximum graphics settings, as well as in resource-intensive applications associated with multi-threaded computing, large amounts of data and 3D rendering.
At AMD, this processor will be the eight-core FX-9590, which is inferior in speed to its competitors, but has a lower price.
The best CPU models in different price ranges, depending on the price-quality ratio:
- Budget Intel Celeron G1620, Pentium G3450, AMD A4-7300, A6-7400K
- Mid-level Intel Core i3-6300, Core i3-4160, Core i5-4590, AMD Athlon X4 860K, A8-7600, FX-8320
- High-performance systems Intel Corei7-4790K, Corei7-6700K, AMDFX-9590
More recently, 6th generation Intel processors with the Skylake core (6xxx) began to appear on sale, which will gradually replace the 4th generation Haswell (4xxx). They are produced at 14 nm. technologies with a number of innovative solutions, and will be used in both stationary and mobile systems.
When buying a new product, you should know that its performance will be 10-15% higher than its previous analogues, and the price will be significantly higher.
Based on this logic, it is up to the buyer to decide whether to spend money on a new product, buy an older platform, or wait for a price reduction.
Laptop processors differ from those used in desktop computers due to their reduced power consumption technologies. And although they are removable, the operation of replacing the CPU in mobile devices is extremely rare, so the frequent question is “How to choose a processor for a laptop?” Sounds wrong.
You have to choose a whole device with a number of other parameters. But the principle of choice is this: it is advisable to take Intel as it is cooler, which will help avoid breakdowns and problems with turning on the laptop. The rest is similar to computers.
Budget systems are Celeron, Pentium; optimal Core i3, i5; gaming Core i5, i7, the marking of which should be “4xxx”, this means a 4th generation stone, which guarantees high speed.
Remember a few rules:
- Depending on the packaging, there will be a different warranty period for the same model. Thus, BOX has a three-year warranty, while OEM has only a year.
- The CPU cooler is supplied based on the nominal thermal package. Overclocking enthusiasts need to take care of purchasing a powerful cooling system.
- The built-in video core will allow you not to spend money on buying a video card, unless the task is to play complex 3D games that, in addition to video cards, also require capacious hard drives.
- All processors have a specific platform, and this determines the different connectors on motherboards. When making a purchase, you need to pay attention to its model and the motherboard for which it is intended.
- High-power CPUs are very power hungry, consuming between 100 and 200 watts of electricity per hour.
When buying a computer, you need to remember that the processor sets the calculation speed, but the speed of the entire system depends not only on it.
There may be some components that will become a bottleneck.
So, with a powerful processor and a slow hard drive, the computer will be slow, the same goes for the video card, memory, etc. The productive system will always be balanced. Following this principle, you can build a powerful computer for relatively little money.
The result is banal: it is impossible to judge the performance of any central processor by only one parameter. Only a set of characteristics gives an understanding of what kind of chip it is. Narrowing down the processors to consider is very easy. AMD's modern ones include FX chips for the AM3+ platform and A10/8/6 hybrid solutions of the 6000 and 7000 series (plus Athlon X4) for FM2+. Intel has Haswell processors for the LGA1150 platform, Haswell-E (essentially one model) for LGA2011-v3 and the latest Skylake for LGA1151.
AMD processors
I repeat, the difficulty in choosing a processor lies in the fact that there are a lot of models on sale. You simply get confused in this variety of markings. AMD has hybrid processors A8 and A10. Both lines include only quad-core chips. But what's the difference? Let's talk about this.
Let's start with positioning. AMD FX processors are top chips for the AM3+ platform. Gaming system units and workstations are assembled on their basis. Hybrid processors (with built-in video) of the A-series, as well as Athlon X4 (without built-in graphics) are mid-class chips for the FM2+ platform.
The AMD FX series is divided into quad-core, six-core and eight-core models. All processors do not have a built-in graphics core. Therefore, for a full build you will need either a motherboard with built-in video or a discrete 3D accelerator.
