To help you make an informed choice, the processor was tested at the NYX Computer Supermarket on 12/18/2017. The test results are visually displayed in a diagram and two tables.
Test stand:
Several proposals for competition. Disputes over the choice of the Intel platform for assembling a gaming system unit from scratch do not subside. Our column "Computer of the month" will serve as proof. With a budget of 50-60 thousand rubles, it is realistic to collect gaming computer with core i5. But which platform should you choose? On the one hand, there is a Core i5-6400 for LGA1151. On the other hand, the sale is full of Core i5-4460 under LGA1150. There are several arguments: the processors cost the same, the Haswell chip runs at a higher clock speed, the transition to Skylake will cost more. Therefore, one of the main motives for this testing was Core comparison i5-6400 with Core i5-4460 in all planes.
The Core i3-6300T chip is opposed to the Core i3-4130. This is a rather old Haswell processor, released back in the third quarter of 2013, but comparable to the energy-efficient T-model in terms of frequency.
Let's start with a RAM test. In the bench for Haswell processors, a dual-channel DDR3-1600 set was used with timings of 9-9-9-28. It is this RAM controller that is integrated into all Core processors fourth generation. Not surprisingly, in the AIDA64 test, Skylake chips were noticeably faster than Haswell, because their integrated DDR4 controller supports RAM with an effective frequency of 2133 MHz. However, in real applications, as our experiment showed, there is practically no difference between DDR3-1600 and DDR4-2133. The current generation of RAM is ruined by very high latency.
An excellent semiconductor basis for assembling a mid-level PC that can solve any problem not only now, but also in the next 2-3 years is the Intel Core i5-6400 processor. This CPU was introduced last year and continues to be up to date with a very high level of performance. Its capabilities will be further considered in detail within the framework of this review material.
Niche of this silicon productIntel's processor products have a strict division into market segments. To products entry level belong to the Celeron line of chips and more productive products of the Pentium lineup. The latter have higher clock speeds and increased L3 cache. The middle segment of the market is assigned to solutions based on i3. All these CPUs have exactly the same as entry-level solutions, only 2 computing modules. But in this case, there is support for HyperTrading technology, which allows you to get 2 times more software streams of information processing. For example, the Intel i3 4170 processor, like any other representative of this family, can process program code in 4 threads at once. The premium segment in this case is occupied by i5 solutions with 4 cores / 6 threads and i7 already with 4 cores and 8 threads. It is to the latter group that the hero of this review belongs. These products provide an unprecedented level of performance and allow you to solve any problem not only now, but in the next 2-3 years for sure.
Various delivery options. Their strengths and purposeThere are two configuration options for this microprocessor product. One of them is an OEM processor. This equipment is minimal and it is aimed at large assemblers of personal computers. It includes:
The processor itself.
A corporate coupon with a guarantee and a multilingual manual for the use of this microprocessor product.
Sticker for the system unit with the name of the processor family.
About the protective box, proprietary cooling system and thermal paste in this case there can be no speech. The new owner of this CPU will have to purchase these components additionally. In this design, this chip is of the greatest interest to computer enthusiasts who plan to overclock their PC. This configuration will allow you to purchase an improved cooling system and thereby achieve stable operation of the system unit after overclocking. The second configuration option for this product is called in the price lists as follows: “Intel Core i5-6400 BOX processor”. In addition to everything previously given, it also includes a protective box for transporting the processor, a standard cooling system and, of course, thermal paste.
This processor is designed for installation in the LGA1151 socket. This computing platform was developed specifically for the 6th generation of Core architecture CPUs and was introduced along with its first representatives in 2016. At the moment, it is relevant and allows you to assemble the most productive personal computers. Also, this processor socket allows you to install more recent chips of the 7th generation. According to Intel's plans, it will be possible to install chips of the 8th generation that have not yet been released into it. So this computing platform will be relevant for at least another 2 years.
Technological aspectsThe hero of this review is produced according to the most advanced technological process, the tolerance standards of which correspond to 14 nm. It is due to this that the products of this family can boast of a very tiny size and impeccable energy efficiency today. In terms of the layout of semiconductor elements on the substrate, this technology is no different from the tolerance standards of 22 nm. As before, the transistors in this case are manufactured using the same TriGate 3D layout technology. Therefore, there are no fundamental differences from previous generations in this regard, and the previous generation Intel i3-4170 processor, for example, has a similar three-dimensional organization of its semiconductor elements.
Like all the most productive semiconductor products from Intel, the hero of this review material boasts a three-level cache of impressive size. The total size of its first level is 128 Kb, which are physically divided into 4 equal parts of 32 Kb each. Each of these parts is aimed at interacting with a strictly defined computing core. It should also be noted that these 32 Kb, in turn, are divided into 2 parts of 16 Kb. One of them can store only instructions of the processor core, and the second - data. The total size of the second level is 1 MB. Like the first level of fast energy memory, the second level is also divided into 4 parts of 256 Kb, assigned to a certain computing resource. In this case, there is no hard division into storing data or instructions. The third level is common to all CPU components - its size is 6 MB.
RAM and its controllerEquipped with an integrated RAM controller (that is, this component of the computing system is located on the silicon chip of the central processor). It can function in and can address up to 64 GB of RAM. Also in the technical specifications appears support for two main types of RAM - DDR3 & DDR4. But it is the last type of RAM that is most safe to use in combination with this chip. If you use DDR3 as part of such a PC, then damage to the RAM controller may occur. Further use of such a PC will be impossible.
The claimed TDP for this chip is 65W. This is a typical value for the entire family of i5 processors of this generation, and it cannot boast of anything unusual in this regard. The maximum allowable temperature for this solution is 71 0 С. In normal mode and when using the standard cooling system, the temperature of this semiconductor solution does not exceed 55 0 С. Well, if you still overclock this CPU, then it is best to refuse to use the standard cooling system and use its more advanced modification from a third-party manufacturer.
Product Frequency ParametersThis semiconductor product uses a frequency control technology based on the temperature of the semiconductor solution and the complexity of the program code being executed, called TurboBust. The minimum frequency in this case is 2.7 GHz and the maximum is 3.3 GHz. Updating the processor architecture also made it possible to increase the speed of the computer system by increasing the frequency. The question of how to overclock an Intel Core i3 or even i5 processor with a locked multiplier (that is, the designation of such processor products does not have the letter “K” at the end) will be discussed in detail later.
The code name for the architecture according to which the processor was developed is Skylake. This is already the 6th generation of chips from the Kor family. At the software level, there is no significant difference between the i3 and i5 CPUs. These central processing units look like four-unit computing solutions. But at the hardware level, they differ significantly. Only 2 physical cores have any Intel Core i3 processor. The CPUs of this family support HT technology, and it is its support that allows you to convert two cores into 4 logical threads at the software level.
But the i5 chips (including the 6400) are full-fledged 4-core solutions. And both at the software and at the logical level. This is what provides a higher level of performance in the latter case. The i5 also has higher frequencies, increased cache levels and support for TurboBust technology. All this in sum in most of the existing software allows you to even compete on an equal footing in terms of performance with more expensive products of the i7 family.
Embedded graphics subsystem of the productAs expected, completed It is on the same semiconductor chip, along with the computing part. This is HD Graphics from Intel model 530. It should be said right away that its computing power is certainly not enough to fully unlock the potential of this CPU. For these purposes, the PC must be equipped with a discrete graphics card. Well, for organizing an entry-level server based on this chip, its presence is more than enough. Its frequency range is limited to 350 MHz - 950 MHz, and the maximum number of connected output screens is 3.
Now let's figure out how to overclock the Intel Core i3 / i5 / i7 processor of the last two generations (that is, the 6th and 7th) with a locked multiplier (there is no letter “K” in their marking). To do this, you must properly equip the PC:
For the motherboard, there must be a special version of the "BIOS", in which it is possible to increase the frequency of the clock generator.
The power supply in this case must have increased power.
Also, RAM must operate at a frequency of 3200 MHz.
Both the system unit and the processor in this case are equipped with an improved, advanced cooling system.
The overclocking algorithm in such a situation is as follows:
We download alternative firmware on the thematic forum and install it in BIOS.
We reduce the frequencies of all PC components, and gradually increase the frequency of the clock generator. After each such increase, we check the stability of the computer.
When a simple increase in frequency is not enough for the stable operation of the computing system, we begin to gradually increase the voltage on the CPU along with the frequency. In this case, the maximum allowable values for voltage and frequency are 1.4-1.425 V and 4.5-4.7 GHz, respectively (40-45% with respect to the original frequency).
The performance processor Intel Core i5-6400 cannot be available. His price is really high - 13,000-15,000 rubles. For the same money you can buy the flagship processor solution from AMD - FX-9370. Only here the difference in performance will be significant, and the second CPU in most modern games will not provide the proper level of performance. Therefore, in such a situation, it seems more justified to buy an average product from Intel than a flagship from AMD. Moreover, most of the modern software is optimized specifically for the CPU from Intel. They now, in essence, have no equal.

Description of test systems and testing methods
The main goal of testing is to identify the performance gain that can be obtained by overclocking non-overclocking processors. Therefore, the younger representatives in the Core i5 and i3 lines, the Core i5-6400 and i3-6100 processors, taken by us for testing, were tested twice: in the nominal operating mode and at a frequency of 4.7 GHz, which, based on the experience gained, can be considered sufficient typical overclocking mode for Skylake generation CPUs. In addition, a full-fledged K-series overclocker processor, the Core i5-6600K, took part in the tests. Its presence in the tests is necessary in order to assess whether the overclocking performance differs between processors intended and not intended for operation in freelance modes, and if so, by how much. We tested the Core i5-6600K twice: both in nominal mode and when overclocked to 4.6 GHz (this is the maximum achievable frequency for our sample with an increase in supply voltage to 1.425 V).
The complete list of components used in the test systems is as follows:
Testing was performed in the operating system Microsoft Windows 10 Enterprise Build 10586 using the following driver set:

So, overclocking, as we knew it a few years ago - before Intel began to release specialized overclocking processors and block the possibility of increasing operating frequencies in other CPUs, is finally back. It is difficult to say where the solution to the issue of removing the blocking of the base clock frequency from the entire Skylake lineup was actually received. Perhaps Intel's BCLK Governor protection turned out to be not so strong and fell under the onslaught of motherboard BIOS developers. But it is also possible that Intel itself pushed them in the right direction, because in the end everyone won: the microprocessor giant, the motherboard manufacturers, and users.
Indeed, thanks to the overclocking opportunities that have opened up, buyers have new arguments in favor of switching to the LGA1151 platform. There is no doubt that this will stimulate sales of new processors to a certain extent. Along the way, new customers will also be received by board manufacturers, who will certainly be able to increase sales of models by Intel-based Z170. Users from among enthusiasts will not remain for nothing either. Before them opens not only additional scope for experimentation, but also the opportunity to extract quite obvious financial benefits. After all, now overclocking systems can be assembled from cheaper components than before.
But the special piquancy of this whole situation is given by how well everything turned out for Intel. After all, the discovery of the possibility of overclocking any, including non-overclocking, LGA1151 processors could easily cause a drop in demand for the flagship Skylake models. However, sales of older Skylake with officially approved overclocking are safe. The fact is that when overclocking non-K processors, a whole bunch of problems suddenly arise, the worst of which is a decrease in the execution speed of AVX/AVX2 instructions. As a result, the performance when working with a number of programs during overclocking not only does not increase, but, on the contrary, falls. That is, the real benefit from such overclocking can be extracted only in cases where it is only about working in applications that do not use the modern capabilities of the processor FPU.
All this means that if we are talking about professional activities for which the performance of CPUs operating in the nominal mode is not enough, you can choose, as before, only from the Core i5-6600K or Core i7-6700K. Overclocking non-K processors is actually only suitable for playing around - in both senses of the word. On the one hand, experimenting with overclocking such processors is insanely interesting, because this is really something new and somewhat forbidden. On the other hand, games are among those applications that AVX/AVX2 instructions (yet?) do not use.
However, even if you are only interested in games and programs where AVX / AVX2 extensions are not used and obviously will not be used, the overclocking capability that appeared in the non-overclocker processors of the Skylake generation does not mean at all that you, figuratively speaking, will be able to rewind time back and return to the golden age of the Celeron 300A. In the realities of today, it is impossible to increase the performance of a cheap processor to the level of a flagship under any circumstances. After Intel divided the range of consumer processors into classes according to the number of computing cores and the list of supported technologies in the mid-2000s, any “class struggle” has irrevocably become a thing of the past. And this is clearly shown by the tests. The younger Core i3-6100 can only claim to try to reach the speed of the initial Core i5 models during overclocking. And the younger Core i5-6400 can try to compete with the Core i5-6600K, but, of course, it is beyond its strength to aim at rivalry with the Core i7-6700K.
