2 June Intel announced ten new 14nm desktop and mobile processor families Intel Core fifth generation (codenamed Broadwell-C) and five new 14nm processor family Intel Xeon E3-1200 v4.
Of the ten new Intel processors 5th Generation Core (Broadwell-C) for desktop and mobile only two processors are targeted at desktop PCs and have an LGA 1150 socket: these are quad-core Intel models Core i7-5775C and Core i5-5675C. All other 5th Gen Intel Core processors are BGA and are aimed at notebooks. Brief characteristics new processors Broadwell-C are presented in the table.

| 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 to 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 | Frequency nominal / maximum, 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, the choice, of course, is small, especially when you consider that the Intel Xeon E3-1200 v4 family processors are focused on servers, not user PCs.
In the future, we will focus on reviewing the new 14nm processors with the LGA 1150 socket.
So, the main features of the new fifth generation Intel Core processors and processors of the Intel Xeon E3-1200 v4 family is the new 14-nanometer microarchitecture of the cores, 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 a 14-nanometer version. Rather, it is a slightly improved Haswell microarchitecture. However, Intel always does this: when switching to a new manufacturing process, changes are also made to the microarchitecture itself. In the case of Broadwell it comes 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 of 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 emphasize once again that we are talking only about cosmetic changes to the Haswell microarchitecture, and therefore, one should not expect that Broadwell processors will be more productive than Haswell processors. Of course, the transition to a new technical process made it possible to reduce the power consumption of processors (at the same clock frequency), but you should not expect any significant performance gains.
Perhaps the most significant difference between the new Broadwell processors and Haswell is the Crystalwell L4 cache. Let's clarify that such an L4 cache was present in Haswell processors, but only in top models mobile processors, and the Haswell desktop processors with the LGA 1150 socket did not.
Let us remind you that in some top-end models of mobile Haswell processors Iris Pro graphics core was implemented with additional memory eDRAM (embedded DRAM), which made it possible to solve the problem of insufficient throughput memory used for the GPU. EDRAM was a separate die that sits on the same substrate as the processor die. This crystal was codenamed Crystalwell.
The eDRAM was 128MB in size and was manufactured in a 22nm process. But the most important thing is that this eDRAM memory was used not only for the needs of the GPU, but also for the computational cores of the processor itself. That is, in fact, Crystalwell was an L4 cache shared between the GPU and the processing cores of the processor.
All new Broadwell processors also include a separate 128MB eDRAM die that acts as an L4 cache and can be used by the graphics and processing cores of the processor. Moreover, we note that the eDRAM memory in 14nm Broadwell processors is exactly the same as in the top mobile processors Haswell, that is, it is performed using a 22-nanometer process technology.
The next feature of the new Broadwell processors is the new graphics core, codenamed Broadwell GT3e. For desktop and mobile processors (Intel Core i5 / i7), this is Iris Pro Graphics 6200, and for Intel Xeon E3-1200 v4 processors, this is Iris Pro Graphics P6300 (excluding Xeon E3-1258L v4). We will not delve into the architecture of Broadwell GT3e graphics cores (this is a topic for a separate article) and will only briefly consider its main features.
Recall that the Iris Pro graphics core was previously present only in Haswell mobile processors (Iris Pro Graphics 5100 and 5200). Moreover, in the graphics cores Iris Pro Graphics 5100 and 5200 there are 40 executive units (EU) each. The new graphics cores Iris Pro Graphics 6200 and Iris Pro Graphics P6300 are already endowed with 48 EUs, and the EU organization system has also changed. Each individual block GPU contains 8 EUs, and the graphic module combines three graphic blocks. That is, one graphics module contains 24 EU, and the Iris Pro Graphics 6200 or Iris Pro Graphics P6300 itself combines two modules, that is, we get 48 EU in total.
As for the difference between the graphics cores 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 proceeding to a detailed examination of the Broadwell test results, let's talk 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 cannot say that any board based on Intel chipset The 9-series will support these new Broadwell processors, but most boards do. However, for this you have to update the BIOS on the board, and the BIOS must support the new processors. For example, for testing we used the ASRock Z97 OC Formula board and without BIOS updates the system worked only if there was discrete graphics card, and the image output through the graphics core of the Broadwell processors was not possible.
The next feature of the new Broadwell processors is that the Core i7-5775C and Core i5-5675C models have an unlocked multiplication factor, that is, they are focused on overclocking. In the Haswell family of processors, such unlocked multiplier processors 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 (they cannot increase the multiplication factor).
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, only the Xeon E3-1285L v4 processor is missing, which differs from the Xeon E3-1285 v4 only in lower power consumption (65 W instead of 95 W) and the fact that the nominal clock frequency its cores are slightly lower (3.4 GHz instead of 3.5 GHz). In addition, for comparison, we also added Intel Core i7-4790K, which is 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 to testing new products.
Test bench
To test the processors, we used the bench with the following configuration:
Testing technique
Processors were tested using our scripted benchmarks, and. More precisely, we took the workstation testing methodology as a basis, but expanded it by adding tests from the iXBT Application Benchmark 2015 package and the iXBT Game Benchmark 2015 game tests.
Thus, to test the processors, we used following applications and benchmarks:
- 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, for testing, we used games and game benchmarks from the iXBT Game Benchmark 2015 package. Testing in games was carried out at a resolution of 1920 × 1080.
Additionally, we measured the power consumption of the processors in idle and stressed mode. For this, a specialized hardware and software complex was used, connected to the break in the power supply circuits of the motherboard, that is, between the power supply and the motherboard.
To create a stressful CPU load, we used the AIDA64 utility (Stress FPU and Stress GPU tests).
Test results
Power consumption of processors
So, let's start with the results of testing processors for power consumption. The test results are presented in the diagram.
The most gluttonous in terms of power consumption, as expected, turned out to be the Intel Core i7-4790K processor with a declared TDP of 88 W. Its real power consumption under stress load was 119 W. At the same time, the temperature of the processor cores was 95 ° C and throttling was observed.
The next in terms of power consumption was the Intel Core i7-5775C processor with a declared TDP of 65 W. For this processor, the stress-load power consumption was 72.5 watts. The core temperature of the processor reached 90 ° C, but throttling was not observed.
The third place in terms of power 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 power consumption was the Intel Xeon E3-1265L v4 processor with a TDP of 35 W. In stress 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, then we must admit that Broadwell has significantly more low 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 the 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 a reference.

| Integral performance result, points | 259,1 | 226,8 | 212,8 | 237,6 | 262,7 |
So, as can be seen from the test results, in terms of integrated performance, the Intel Xeon E3-1285 v4 processor practically does not differ from the Intel Core i7-4790K processor. However, this is an integral result for the totality of all applications used in the benchmark.
However, there are a number of applications that take advantage of the Intel Xeon E3-1285 v4 processor. These applications include MediaCoder x64 0.8.33.5680 and SVPmark 3.0 (video converting and processing), Adobe Premiere Pro CC 2014.1 and Adobe After Effects CC 2014.1.1 (creating video content), Adobe Photoshop CC 2014.2.1 and ACDSee Pro 8 (processing digital photos). In these applications, the higher clock speed of the Intel Core i7-4790K processor does not give it an edge 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 here, tests based on Adobe applications Illustrator CC 2014.1.1 and Adobe Audition CC 2014.2 use less processor cores (in comparison with other applications).
And of course, there are tests in which the Intel Xeon E3-1285 v4 and Intel Core i7-4790K processors show the same performance. For example, this is a test based on WinRAR 5.11 application.
In general, it should be noted that the Intel Core i7-4790K processor demonstrates higher performance (in comparison with the Intel Xeon E3-1285 v4 processor) precisely in those applications in which not all processor cores are used or the core load is not full. 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.
Calculations in the application Dassault SolidWorks 2014 SP3 (Flow Simulation)
Test based on Dassault SolidWorks 2014 SP3 application with additional package We took out Flow Simulation separately, since this test does not use a reference system, as in the tests of the iXBT Application Benchmark 2015.
Recall that in this test we are talking about hydro / aerodynamic and thermal calculations. There are six in total different models, and the results of each subtest is 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 provide 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 a reference.
As can be seen from the test results, in these specific calculations the leadership is on the side of the Broadwell processors. All four Broadwell processors demonstrate faster computation speed compared to the Core i7-4790K processor. Apparently, these specific calculations are influenced by the improvements in the execution units that were implemented in the Broadwell microarchitecture.
SPECapc for 3ds max 2015
Next, let's take a look at the SPECapc for 3ds max 2015 benchmark results for Autodesk 3ds max 2015 SP1. The detailed results of this test are presented in the table, and the normalized results for the CPU Composite Score and GPU Composite Score - in the diagrams. The result of the Core i7-4790K processor is taken as a 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 |
| Interacive 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 |
In the SPECapc 3ds for max 2015 test, Broadwell processors are in the lead. Moreover, if in the subtests that depend on the performance of the CPU (CPU Composite Score), the Core i7-4790K and Xeon E3-1285 v4 processors demonstrate equal performance, then in the subtests that depend on the performance of the graphics core (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 test. 3D modeling- SPECapc for Maya 2012. Recall that this benchmark was run in tandem with the Autodesk Maya 2015 package.
The results of this test are presented in the table, and the normalized results are shown in the diagrams. The result of the Core i7-4790K processor is taken as a 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 performs slightly better than the Core i7-4790K processor, however, the difference is not as significant as in the SPECapc 3ds for max 2015 package.
POV-Ray 3.7
In the POV-Ray 3.7 test (rendering 3D model) the leader is the Core i7-4790K processor. V 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 ambiguous. In the OpenGL test, all Broadwell processors significantly outperform the Core i7-4790K processor, which is natural, since they have a more powerful graphics core integrated. 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 SPECviewperf v.12.0.2 tests, the results are determined primarily by the performance of the processor's graphics core and, moreover, by the optimization of the video driver for certain applications. Therefore, in these tests, the Core i7-4790K processor significantly lags behind the Broadwell processors.
The test results are presented in the table, as well as in normalized form in the diagrams. The result of the Core i7-4790K processor is taken as a reference.
| Test | Xeon E3-1285 v4 | Xeon E3-1265L v4 | Core i5-5675C | Core i7-5775C | Core i7-4790K |

This is not to say that everything is unambiguous in this test. In some scenarios (Media and Entertainment, Product Development, Life Sciences), more high score showcase Broadwell processors. 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 in conclusion, consider the results of testing processors in gaming tests... As a reminder, we used the following games and gaming benchmarks for testing:
- 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 1920 × 1080 and in two settings modes: maximum and minimum quality. The test results are presented in the diagrams. In this case, the results are not standardized.
In gaming tests, the results are as follows: all Broadwell processors demonstrate very similar results, which is natural, since they use the same Broadwell GT3e graphics core. And most importantly, with the settings for the minimum quality, Broadwell processors allow you to comfortably play (at FPS over 40) in most games (at a resolution of 1920 × 1080).
On the other hand, if the system uses a discrete graphic card, then there is simply no point in the new Broadwell processors. That is, it makes no sense to change Haswell to Broadwell. And the price of Broadwells is not so attractive, which would be very 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 on the way Skylake processors, so it is unlikely that the Intel Core i7-5775C and Core i5-5675C processors will be in special demand.
Server processor family Xeon E3-1200 v4 is a separate segment of the market. For most ordinary home users, such processors are not of interest, but in the corporate sector of the market, these processors may be in demand.
Hello everyone guys Intel Core i3, i5, i7 processors, this is perhaps the best middle among processors in the world. Yes, guys, in the world, if you need an optimal balance in terms of price and performance, then it is better to take the process from Intel. I do not argue, AMD is also good, but in short, they have a lot of cores and the frequency is higher, but they are still weaker .. And, you know what? Do not forget that AMD processors consume more light .. For some, this is a trifle, but for others it will be important ..
So, off topic a bit, so sorry. The question we have today is, how many cores are there in the Core i5 process? And here the answer cannot be taken and just given! Why? Prots can be laptop, desktop and, so to speak, the first i5 models. For all these three types, the number of cores may differ, and there may even be threads (Hyper-threading technology). Although there are such users, they are sure that there are no threads in i5, period, no and that's it! In a sense, they are right, because there are no streams in the desktop versions (we'll talk about the exception later).
So guys, in general, if you have an i5 percent, then you can not guess and not fool yourself, you can just take and download CPU-Z utility, she will show you everything. Then you run the CPU-Z program, and down there there is something like Cores and Threads, these are the cores and threads, this is where it is written:
But if you are just interested in infa about how many cores there are in Intel Core i5, then guys, I’ll tell you.
So, as I already wrote, desktop versions of Core i5 have 4 cores. This is the golden mean among Intel processors, 4 cores and everything, without threads. i7 already comes with threads, but there are also 4 cores. Well, i3 doesn't have 4 cores, it has 2 cores, but it also has threads.
It has already happened that in the i5 process there are 4 cores, period. But, this all applies to the desktop versions. But there is one exception on socket 1156, well, maybe there is not one exception, but several, well, the first i5 processes on socket 1156 had 2 cores and 4 threads. That is, they were i5 with 2 cores, many users will say that I am writing a complete bullshit, but it's true. Here is an example, the i5 650 model in the CPU-Z program:
See what is written down there? Cores: 2 and Threads: 4, which means two cores and four threads. But don't you worry if you regular user, then I think that it is unlikely that you will have such a percentage, after all, 1156 socket is already in the past, this is an outdated socket and a little rare. These are the exceptions, all other i5 models are on the 1155 socket, on the 1150, on the 1151, then there are already 4 cores as standard everywhere.
Now about mobile processors. If you have a laptop, or you are thinking of taking it, then you should know that inside the laptop there is not the same percentage as in a regular computer. It stands there for a laptop, and is made so that the laptop works for a long time, so that the percentage does not eat a lot of light, does not warm up and so on. It is clear that this all affects performance, this percentage is less productive than the desktop version. Sometimes, you can even say that it is truncated, because there are not 4 cores but 2, but there are threads. For example, the Core i5-4200U model:
As you can see, this is exactly what I was talking about, there are 2 cores and 4 threads, although this is i5! Here is another i5-6200U model, newer, but still there are 2 cores 4 threads:
So laptop processors are like that, well, a little different.
If the laptop is expensive, then there may be an i5, which has all full-fledged 4 cores, but alas, they still remain mobile. For example, the i5-6300HQ model:
By the way, the situation is about the same with the Core i7, there are also differences in terms of the number of cores!
Well guys, more or less okay, everything I wrote to you here? I hope that everything was clear here, but if something is wrong, then I'm sorry. You see, I bring screenshots of the CPU-Z program everywhere, this is because it is a good program and I recommend it to you, this is a great program to quickly find out information about the process. It is free, the computer does not load at all, it works well, in short, I wrote that this is a good program
All the guys, that's all, good luck in your life, so that everything is good for you, so that you do not get sick and be happy, good luck
09.12.2016This article will take a closer look at the latest generations of Intel processors based on the Cor architecture. This company occupies a leading position in the market computer systems, and most PCs are currently assembled on its semiconductor chips.
Intel development strategy
All previous generations of Intel processors were subject to a two-year cycle. A similar strategy for releasing updates from this company was called "Tik-Tak". The first stage, called "Tick", was the transfer of the CPU to a new technological process. For example, in terms of architecture, the Sandy Bridge (2nd generation) and Eevee Bridge (3rd generation) generations were virtually identical. But the production technology of the former was based on 32 nm, and the latter - 22 nm. The same can be said about Haswell (4th generation, 22 nm) and Broadwell (5th generation, 14 nm). In turn, the "So" stage means a radical change in the architecture of semiconductor crystals and a significant increase in performance. An example is the following transitions:
1st generation Westmere and 2nd generation Sandy Bridge. Technological process in this case it was identical - 32 nm, but the changes in terms of the chip architecture are significant - the north bridge of the motherboard and the built-in graphics accelerator transferred to the CPU.
3rd generation Ivy Bridge and 4th generation Haswell. The power consumption of the computer system has been optimized, the clock frequencies of the chips have been increased.
5th generation Broadwell and 6th generation SkyLike. The frequency has been increased again, the power consumption has been further improved, and several new instructions have been added to improve performance.
Segmentation of processor solutions based on the Cor architecture
Intel central processing units are positioned as follows:
Most available solutions- these are Celeron chips. They are suitable for assembly office computers, which are designed to solve the most simple tasks.
The CPU of the Pentium series is one step higher. V architectural plan they are almost completely identical to the younger Celeron models. But the increased cache of the 3rd level and higher frequencies give them definite advantage in terms of performance. The niche of this CPU is gaming PCs entry level.
The middle segment of Intel CPUs is occupied by solutions based on Cor I3. The previous two types of processors, as a rule, have only 2 computing units. The same can be said about Kor Ay3. But the first two families of chips lack support for the HyperTrading technology, while Cor Ay3 does. As a result, at the software level, 2 physical modules are converted into 4 program processing threads. This provides a significant increase in performance. On the basis of such products, it is already possible to assemble a mid-level gaming PC, or even an entry-level server.
The niche of solutions above the average level, but below the premium segment is filled with chips, occupied by solutions based on "Kor Ay5". This semiconductor crystal boasts 4 physical cores at once. It is this architectural nuance that provides an advantage in terms of performance over Kor Ay3. More recent generations of Intel i5 processors have higher clock speeds and this allows for continuous performance gains.
The niche of the premium segment is occupied by products based on Kor Ay7. The number of computing units they have is exactly the same as that of "Kor Ay5". But they, just like Cor Ay3, have support for the technology code-named Hyper Trading. Therefore, at the software level, 4 cores are converted into 8 processed threads. It is precisely this nuance that provides a phenomenal level of performance that any one can boast of. The price of these chips is appropriate.
Processor connectors
Generations are set in different types sockets. Therefore, it will not be possible to install the first chips on this architecture into a motherboard for a 6th generation CPU. Or, on the contrary, the chip with the code name "SkyLike" physically cannot be put into system board for 1st or 2nd generation processors. The first processor socket was called Socket H, or LGA 1156 (1156 is the number of pins). It was released in 2009 for the first CPUs manufactured to 45 nm (2008) and 32 nm (2009) tolerances based on this architecture. Today it is outdated both morally and physically. In 2010, LGA 1155 comes to replace, or "Socket H1". Motherboards of this series support 2nd and 3rd generation Cor chips. Their codenames are, respectively, "Sandy Bridge" and "Ivy Bridge". 2013 was marked by the release of the third socket for chips based on the Cor architecture - LGA 1150, or Socket H2. This socket could accommodate 4th and 5th generation CPUs. Well, in September 2015, the LGA 1150 was replaced by the last actual socket - LGA 1151.
The first generation of chips
The most affordable processor products on this platform were the Celeron G1101 (2.27 GHz), the Pentium G6950 (2.8 GHz) and the Pentium G6990 (2.9 GHz). All of them had only 2 cores. The niche of middle-level solutions was occupied by "Kor Ay3" with the designation 5XX (2 cores / 4 logical flows of information processing). “Kor Ay5” marked 6XX (their parameters are identical to “Kor Ay3”, but the frequencies are higher) and 7XX with 4 real cores were one step higher. The most productive computer systems were assembled on the basis of "Kor Ay7". Their models were designated 8XX. The fastest chip in this case was labeled 875K. Due to the unlocked multiplier, it was possible to overclock the same price, he had a corresponding one. Accordingly, it was possible to get an impressive increase in performance. By the way, the presence of the "K" prefix in the designation of the CPU model meant that the multiplier was unlocked and this model could be overclocked. Well, the prefix "S" was added in the designation of energy efficient chips.
Planned renovation of architecture and "Sandy Bridge"
The first generation of chips based on the Cor architecture was replaced in 2010 by solutions codenamed Sandy Bridge. The key "chips" were the transfer north bridge and an integrated graphics accelerator on a silicon die of a silicon processor. Niche most budget decisions occupied the "Celerons" of the G4XX and G5XX series. In the first case, the L3 cache was cut and only one core was present. The second series, in turn, could boast of having two computing units at once. The Pentiums of the G6XX and G8XX are one step higher. In this case, the difference in performance was provided by the higher frequencies. It was the G8XX that looked preferable in the eyes of the end user because of this important characteristic. The Kor Ay3 line was represented by the 21XX models (the number 2 indicates that the chip belongs to the second generation of the Kor architecture). Some of them had a "T" at the end - more energy efficient solutions with reduced performance.
In turn, the Kor Ay5 solutions were designated 23XX, 24XX and 25XX. The higher the model mark, the higher the level of CPU performance. The “T” at the end is the most energy efficient solution. If the letter "S" is added at the end of the name - an intermediate version in terms of power consumption between the "T" - the version of the chip and the standard crystal. Index "P" - the graphics accelerator is disabled in the chip. Well, the chips with the letter "K" had an unlocked multiplier. This marking is also relevant for the 3rd generation of this architecture.
The emergence of a new, more progressive technological process
In 2013, the 3rd generation of CPUs based on this architecture was released. Its key innovation is an updated technical process. For the rest, no significant innovations were introduced into them. They were physically compatible with the previous generation of CPUs and could fit into the same motherboards. Their designation structure remained identical. The Celerons were designated G12XX and the Pentiums were designated G22XX. Only at the beginning, instead of "2" was already "3", which indicated belonging to the 3rd generation. The Kor Ay3 line had 32XX indexes. More advanced "Kor Ay5" were designated 33XX, 34XX and 35XX. Well, the flagship solutions "Kor Ay7" were marked 37XX.
The fourth revision of the architecture "Cor"
The next stage was the 4th generation of Intel processors based on the Cor architecture. The marking in this case was as follows:
The Celerons economy class CPUs were designated G18XX.
Pentiums had the G32XX and G34XX indexes.
The following designations were assigned to "Kor Ay3" - 41XX and 43XX.
“Kor Ay5” could be recognized by the abbreviations 44XX, 45XX and 46XX.
Well, for the designation "Kor Ay7" 47XX were allocated.
Fifth generation of chips
based on this architecture, it was mainly focused on use in mobile devices... For desktop PCs, only chips of the Ay 5 and Ay 7 lines were released. And only very limited quantity models. The first of them were designated 56XX, and the second - 57XX.The most recent and promising solutions
The 6th generation of Intel processors debuted in early fall 2015. This is the most relevant processor architecture currently. Entry-level chips are designated in this case G39XX ("Celeron"), G44XX and G45XX (this is how Pentiums are labeled). The Kor Ay3 processors are designated 61XX and 63XX. In turn, "Kor Ay5" is 64XX, 65XX and 66XX. Well, only the 67XX marking is allocated for the designation of flagship solutions. The new generation of Intel processors is only at the beginning of its life cycle and such chips will remain relevant for quite a long time.
Overclocking features
Almost all chips based on this architecture have a locked multiplier. Therefore, overclocking in this case is possible only by increasing the frequency.In the last, 6th generation, even this possibility of increasing the speed will have to be disabled in the BIOS by manufacturers motherboards... The exception in this regard are the Kor Ay5 and Kor Ay7 series processors with the K index. Their multiplier is unlocked and this allows you to significantly increase the performance of computer systems based on such semiconductor products.
Owners opinion
All generations of Intel processors listed in this material have a high degree of energy efficiency and a phenomenal level of performance. Their only drawback is their high cost. But the reason here is that Intel's direct competitor, AMD, cannot oppose it with more or less worthwhile solutions. Therefore, Intel is already proceeding from its own considerations and sets a price tag for its products.
Outcomes
This article took a closer look at Intel desktop-only processor generations. Even this list is enough to get lost in designations and names. Apart from this, there are also options for the computer enthusiast (platform 2011) and various mobile sockets. All this is done just to end user I could choose the most optimal one for solving my problems. Well, the most relevant now from the considered options are chips of the 6th generation. These are the ones to look out for when buying or assembling a new PC.

In the model a number of Intel Core there are devices not only with the "K" index, but also with "T". And, if everything is very clear with the first letter (these are CPUs with an unlocked multiplier, designed for overclocking), then some users have never heard of the second solutions.
Maximum multiplier y Intel Core i5-7400T- 30, this means that all 4 physical cores can actually be started at 3000 MHz.
Actually key feature at T-processors one - low power consumption (and hence heat dissipation). As a rule, this is a CPU with a reduced clock speed, but with exactly the same number of physical cores and threads compared to solutions without a characteristic letter in the marking.
Here is the guest of today's review under Intel name The Core i5-7400T is essentially classic 4-core processor with full cache size; the characteristics of this modification are no different from the well-known Intel variant Core i5-7400, apart from two key parameters (lower clock speed and modest TDP, not exceeding 35W).
Believe it or not, Intel actually managed to create a 4-core processor with a sufficiently high clock speed (in automatic mode only one core operates at 3 GHz), while keeping within 35 W thermal package.

Everything central processing units, in the name of which there is the letter "T", are not intended for use in extreme systems and overclocking PCs. There are certainly no hardware limitations, it's just not practical.
Why buy a slow (albeit cold) processor when you can buy a CPU with better specs for the same price? By the way, Intel version Core i5-7400 and the same model, but with the "T" index, retail are the same.
Technical features
So, the 14 nm Intel Core i5-7400T has four physical cores (the same number of computing threads, Hyper-Threading technology is not used), 6 MB of L3 cache and an integrated Intel HD Graphics 630 graphics core. The processor is compatible with dual-channel DDR4-2133 RAM / 2400 and DDR3L-1333/1600.
We used the Cooler Master X Dream P115 cooler to cool this CPU.
The nominal clock speed of all 4 physical cores is 2400 MHz, in the Turbo Boost one of them accelerates to 3 GHz (if you wish, you can start at 3000 MHz and all four, we'll talk about this below). And, as mentioned above, the declared TDP of the device is 35 W.
In fact, in some cases (under high load) this figure jumps to more significant values, for example, we were able to capture 75 watts in the Corona 1.3 Benchmark test. But these are short-term peaks, most of the time monitoring programs do not show indicators above 30 watts.
Intel Core i5-7400T nominal 
Intel Core i5-7400T @ 3050 MHz (all 4 cores)
Intel Core i5-7400T and DDR4-2933 memory
Obviously, the Intel Core i5-7400T is very cold processor, still working voltage stone- 0.912 V, and the clock speed is 2400 MHz. We used the Cooler Master X Dream P115 cooler to cool this CPU. Eventually Maximum temperature that we recorded did not exceed 45 degrees (under the most severe load). By the way, the processor under exactly the same CO heats up to similar values (it has 2 cores and 51 W TDP).

Performance and test results
Four active physical cores help the reviewed processor compete on an equal footing with high-frequency CPUs, which have two cores and 4 processing threads. The truth is not in those applications where the performance of a single core is key. For example, in Cinebench R15 the Intel Core i5-7400T demonstrates a higher result compared to, but in WinRAR and Corona 1.3 it does not.
Therefore, before choosing an Intel Core i5-7400T for a particular system, it is worthwhile to outline the range of tasks that will be performed using such a PC. Perhaps for your purposes, first of all, a high clock frequency is required, and not 4 physical cores.
For swinging a powerful graphics adapter and up-to-date gaming, the Intel Core i5-7400T fits perfectly. And here four physical cores just play a key role, because the clock frequency of the processor in toys is not so significant (especially in high resolutions). Yes, the extra megahertz allows you to achieve the maximum frame / s, but your eye still won't be able to catch the difference between 60 and 80 fps, believe me.
Overclocking
In the arsenal of Intel Core i5-7400T there is one extremely useful cunning, allowing you to increase processor performance by 5-8% if you need it. The maximum multiplier of the monitored stone- 30, this means that all 4 physical cores can actually be started at 3000 MHz (for this, you must manually select this value in the UEFI BIOS). True, the TDP in this mode will no longer correspond to 35 W, it will grow.
Via functional module TPU II, which is soldered to ASUS Maximus IX Extreme, Intel Core i5-7400T overclocked to 3050 MHz, and this is the limit for our configuration.
Conclusion
Intel Core i5-7400T without any "buts" is a full-fledged 4-core processor that perfectly copes with multimedia tasks in home and gaming PCs. Together with that stone it is advisable to install in the system top-end video card if you are mainly interested in gaming applications.
For " swinging " a powerful graphics adapter and up-to-date gaming, the Intel Core i5-7400T fits perfectly.
Although for a PC that already has one cold element, it is reasonable to look for an accelerator with a low TDP (and even with passive system cooling) to minimize the number of fans inside the computer case.
As a result, you can count on a completely silent, energy efficient, and most importantly cold PC (no compromise on performance); similar systems in our time are becoming more and more popular.
