Hello everyone The moment has come when we will talk about processors. In general, processors are one of my favorite topics, there was a time when I was a powerful fan of processors and knew everything about them, although now this information is not very relevant, but still... By the way, this was all in the days of the Pentium 4, which have long been in the past... antiquity in general... but it’s a little offensive, it’s probably nostalgia...
And the memory voltage must exceed 65 volts; anything larger could damage the processor. Although these may seem like an inconvenience, they do not provide any benefits. If you don't need to use all the processor cores at any given time, the ones you don't need will be disabled, reducing heat dissipation and automatically increasing the capacity of the remaining cores. And in case multi-processing isn't enough for you, the technology can support up to eight physical cores, meaning 16-core processing might not be that far off.
Today we will have a conversation, so to speak, not only about the i7-7700K processor, but in general we will touch on some other points. I will also compare the i7-7700K with the previous similar model, this is the i7-4790K, which comes on the 1150 socket. By the way, you probably know, but let me remind you that the i7-7700K is a modern and top-end processor on the 1151 socket platform with an unlocked multiplier

- Some features and configurations are not available in all regions.
The main difference, or rather not the main thing, but so to speak, a noticeable difference between the 1150th socket and the 1151st is that the first supports 32 gigabytes of DDR3 Opera maximum, and the second already supports 64 gigabytes of DDR4 Opera. Although, to be honest, I don’t know where you can see the difference between DDR3 and DDR4, it’s still modern types memory.. Well, that’s it, specialists may see the difference...
This document details some key features and their impact on testing, measurement and control applications. Figure 1. However, this impact is much more significant for multiprocessor systems. For achievement maximum performance in a multiprocessor system, the application software must be multithreaded and aware of this new architecture. Since then, many applications and development environments have been expanded to take advantage of multiple processing elements in a system.
However, due to the investment in software required to re-archive applications, there are still a significant number of applications that are single threaded. Figure 3. When idle, all four cores are running at their base clock speed. If an application is initiated that creates four discrete threads of execution, all four processing cores start running at quad-core turbo frequency. If an application only creates two threads of execution, then the two idle cores are placed in a low-power state and their power is diverted to the two active cores so they can run at an even higher clock speed.
The i7-7700K comes with the letter K, but what does it mean? Well, you probably know, but maybe you don’t know! Everything is logical here, the letter K means that the multiplier is unlocked and the percentage can be driven, only the motherboard must not let us down with this matter. The same applies to the i7-4790K
I also want to tell you that you know what prompted me to write this article? I myself have a platform on the 1150th socket, an expensive motherboard, because I borrowed it for a long time and then bam, the 1151st socket comes out, now I’m racking my brains about what to do, I finally want a powerful computer for a long time: switch to the 1151st socket or stay on the 1150 and take the i7-4790K, of course I’m more attracted to the second option..
This behavior will apply when applications generate only one thread of execution. This feature improves overall processor performance and is beneficial for a variety of applications including testing, measurement, and control.
In the field of test, measurement and control, engineers and scientists have used this technology to combine individual computing nodes into a single system. These improvements, combined with an increase bandwidth memory and processing performance enable engineers and scientists to create more advanced and complex virtualized systems for testing, measurement and control.
On a note! Here is a screenshot of the CPU-Z program showing information about the i7-7700K:
So, first of all, we’ll probably start with the fact that the i7-7700K is a 2017 percent, it’s still damn modern, and the i7-4790K is a 2014 percent, which isn’t that old either. Or should I remind you of the fans of the 775 socket and in particular the Q9650 processor?
This feature allows administrators to boot systems from remote media, monitor hardware and software assets, and perform remote troubleshooting and recovery. Engineers can use this feature to manage deployed automated test or control systems that require high uptime. This allows the problem to be resolved earlier and no longer requires interaction with the real system.
Engineers and scientists can expect increased processing performance, as well as increased memory and data throughput when comparing this microarchitecture to previous microarchitectures. Any change in any of these factors could cause the results to change.
The second important or not particularly important point is that the i7-7700K is made using a 14 nm process technology, yes, that’s cool, but is 22 nm really that bad? Too bad it’s 45 nm, it seems to me! Well, 32 nm is also not very good... but 22 nm, I think this is normal. Honestly guys, that’s how I think and write. For me, what is 22 nm and what is 14, I think these are still modern technical processes!
Price. Well, for now, now it’s 2017 and, in principle, the price is almost the same, the i7-7700K is more expensive, but a little, no, I confused this with just the i7-4790! And the price for the i7-4790K is the same as the i7-7700K!
Technological process. Energy efficiency. Specifications regarding power consumption
You should consult other information and performance tests to assist you in fully evaluating your intended purchases, including the performance of this product in combination with other products. Contact your system manufacturer or retailer. Performance varies depending on system configuration. No computer system can be completely secure.
Contact your system manufacturer or retailer for more information. Measure and calculate the average power for the duration of the video. Is a realistic scenario of actual performance in current games? We can draw two big conclusions from the tests. So how close does our benchmarking get to actual gameplay? But in reality, benchmarks are just a way of testing performance under the same conditions, and of course, reliability depends on your hardware components.
Let's move on. Cores and threads, you don’t need to write anything here, both processors have 4 cores and support Hyper-threading technology, that is, in the end, each processor has 8 threads, everything is standard here. Well, in principle, even the numbers are similar in the sockets: 1150 and 1151, as a hint that this is not a radically new platform, but an improved 1150. Well, that’s my opinion!
We come to the most interesting thing, this is the clock frequency. The i7-4790K has 4 GHz and in turbo boost it increases to 4.40 GHz, which is actually quite good! For the i7-7700K it is 4.20 GHz as standard, and in turbo boost it rises to 4.50 GHz. Well, yes, a little higher.. But is this really a reason to change the platform? Hmm, probably not. Moreover, instead of replacing the platform, you can buy water cooling and overclock the i7-4790K to 4.8 GHz, and be a happy person. And this, you can even order a scalp i7-4790K to install liquid metal, then there will be a bomb even with air cooling... Only 32 gigabytes of opera at most is a little upsetting..
And there are other reasons why you should have one. But it's equally clear that the lack of innovation in the processor core is itself a problem. Our tests show that pushing beyond this threshold offers fairly limited benefits, and the downside is both heat and additional power consumption.
It's also worth noting that CPU and gaming performance aren't the only potential reasons for upgrading. You can buy it safely, whether it is the best product in its market group on this moment. Faster task processing is appreciated when using in the office, but also when playing games.
Cache. There is no point in writing anything here, everything is the same, both processors have 8 megagrams of cache.
Bus frequency. Well, the pancake here is higher for the i7-7700K and is 8 GT/s DMI3, and for the i7-4790K it is 5 GT/s DMI2, well, I don’t know, is it noticeable? Well, is it really terribly noticeable? Probably no yokarny babay!
TDP. Here the i7-4790K has an advantage, because it consumes approximately 88 watts, while the i7-7700K consumes 91 watts. Stop mobile phone, is TDP really consumption? Yes, I know that in fact this is a parameter that determines how much heat needs to be dissipated, that is, how much heat the percent will generate. But if a processor emits 20 watts of heat, then it cannot consume less, right? Well, it seems so.. Although heat is probably not measured in watts.. but that’s not the point
Processor solution niche
This processor is a great choice if you need high performance both for demanding tasks and for multitasking or playing the most complex games. Over the years, the company has been producing some of the best chipsets and processors. This helps resolve compatibility issues software on newer operating systems.
And, of course, he briefly tried to understand what a processor could do under liquid nitrogen. Today we'll be interested in overclocking itself, again as a bit of a tutorial on how to use the platform to get the most out of the chip. However, it is also worth it, twenty threads in the extreme edition of Holt will not set you free. They still have the ability to distribute, they are six-core with active hyperthreading.
Memory. I already wrote. The i7-4790K has a maximum of 32 gigs, DDR3. The i7-7700K has DDR4 and a maximum of 64 gigabytes. This is a controversial point, workstations may actually need all 64 gigs, and I wouldn’t refuse, but what’s the point? I think that for now 32 gigs is enough for me, although I now have 8 gigs and this, well, is not enough for me, this is of course a serious point. I hope that 32 gigs will last me for a long time. Both processors use a maximum of 2 memory channels. Well, in short, I personally don’t see any particular advantage here either, DDR4 is faster, but damn, I don’t know where to notice it, maybe in games? Maybe. But I'm not sure
This is a small thing from my point of view. What remains is voltage control through the built-in controller. Productivity for work is literally brutal. Twenty threads is brutal, although they are relatively low. What is a nice benefit is the ability to disable individual processor cores. This is especially true for extreme overclocking, where you don't need all the cores for some benchmarks.
Summarizing information about the processor, which extracts additional from the additional four additional threads and thus overcomes everything that is currently on the desktop. As an annual product, it also comes with a richer package that includes a great front-facing soundbar with its own sound section.
Built-in graphics core. Well, of course it’s not interesting to gamers, but it’s interesting to people like me. The i7-4790K costs very good Intel core® HD Graphics 4600, well, it's really good! But the i7-7700K has a fundamentally new and more powerful one, this is Intel® HD Graphics 630. And although the stock frequency of the graphics cores is 350 MHz, for the i7-4790K it can rise to 1.25 GHz, and for the i7-7700K up to 1.15 GHz. Although the graphics are different. The i7-7700K's maximum supported monitor resolution is slightly higher, but not significantly. In short, the integration is better on the i7-7700K, no doubt about it
Equipment. Its features
He described the motherboard in detail. We then wait for maximum static acceleration manually and end up testing liquid nitrogen. You can find the comments at the end of the last chapter. But there are other, although not so significant, changes. However, this is a motherboard with a new chipset. . Is the argument enough to change the processor?
Socket. motherboards
The ease of access to components was helpful when running CPU performance tests. By removing the large service cover on the bottom, the most important components are at your fingertips. The processor can be replaced after removing the fan and radiator.
DirectX. There is not much difference here either, the i7-7700K ONLY supports DirectX 12, and the i7-4790K also supports DirectX 11.2.
Well, basically, I showed you the MAIN characteristics of the i7-7700K processor, they are ALMOST the same as those of the i7-4790K. In principle, this can be seen from the price, as I wrote above, it is the same, or almost the same..
In general, according to the tests, well, honestly, yes, then the i7-7700K will still be a LITTLE more productive than the i7-4790K. I think this is understandable and logical.
Just plug in your compatible adapter. Replacing the processor is easy; Two screwdrivers and some thermal pads are enough. In new games, as well as in many non-essential applications, quad-core quad-core processors did much worse than much cheaper and higher-precision dual-core processors.
Some manufacturers knew about this and offered the possibility of factory overclocking, but this was only possible in cases where the laptop had large reserves for heat dissipation. These extreme values vary significantly. Note. This only happens when only one kernel is loaded. If there is a need for all four cores to work, the frequency is reduced to the standard maximum. Since this continuous adjustment is automatic, the user can constantly benefit from maximum performance alternating with optimal energy savings.
Now there are few tests, for some reason there are few of them on the Internet, well, although everything is clear, the percentage is new, they have not yet been properly tested. But I found something, here is the first test of the gaming GTA V Average FPS, as we see here the i7-4790K is still slightly behind the i7-7700K:
You know guys, looking at the FX-8370 here brings tears to my eyes, I wanted an AMD, but I didn’t think that the eight-core FX-8370 would be at the very bottom... it’s just a shame... there are 8 cores and a frequency of 4 GHz and that doesn’t help..
Reviews. The future of this computer platform
The existing division of northern and south bridges cancelled. Memory and graphics controllers are integrated with the processor. The differences compared to the previous architecture are shown in the diagram below. This is a test adapted for older games where the CPU can have a big impact on performance.
Cache memory. RAM subsystem
However, this difference relates to standard deviations. The results correspond to the processor ratings. Overall, however, this test encourages the following conclusion: no matter which processor we choose, its impact on performance in the latest games will be quite limited.
Here is the SYSmark 2014 SE test, here the i7-4790K also lags behind, but not so much.
A processor with phenomenal performance and unique technical specifications and characteristics is the “Cor i7-3820 " It is the capabilities of this semiconductor solution that will be discussed in this material. Test results and owner reviews will also be provided.
In the case of less processor-intensive games, its performance is clearly modest. In these and similar titles, you can expect the most benefit if you believe in the synthetic tests you've done before. Of the four tests, we took the best result.
In general, we can say that both tests show a decrease in processor impact as demands on the processor increase. graphic card. This game's demand for processor power was especially criticized. It took time to develop since the premiere technical solutions capable of meeting high demands.
Semiconductor Solution Niche
The silicon chip in question is a premium-level processor solution. i7-3820. Its performance is truly phenomenal and allows you to solveany tasks. This includes processing complex graphic images This includes programming, video transcoding, and the most demanding and resource-intensive gaming applications. Essentially, a universal processor product is i7-3820. Review samepossible areas of its application indicates that it can form the basis of a graphical PC (in this case, the presence of a specialized video card is mandatory), and implement the functions of a mid-level server, and can even be a gaming system unit with maximum performance. Its only important feature is its high cost. But this nuance extends completely to this entire computing platform.
Equipment. Its features
Like any other modern processor product, it comes in two possible configuration options: i7-3820. More accessible, from a positionand less costly, and less functional, from the point of view of the supply list - TRAIL. Besides the processor device, it also includes a CPU family logo sticker, a warranty card, and a quick start guide for using the semiconductor solution. This configuration option will be optimal choice for computer enthusiasts and large companies that specialize in assembling system units of stationary personal computers.
Second possible variant configuration - BOX. It is complemented by a proprietary cooler and thermal paste. Most often, a similar configuration option is purchased by conventionalaverageusers.
Socket. motherboards
To the processor socketLGA2011must be installed i7-3820. Motherboard in this case it must be based on the chipsetX79. At the same time, there is support only for processors based on the architecture code-named “Kor” of the 2nd and 3rd generations. But more advanced processors of the 4th and even 5th generation with a similar architecture, although they can boast a similar number of contacts, are intended for installation already in processor socket with designationLGA2011-v3.The chipset in this case is X99. That is, these platforms are absolutely incompatible.
Architectural features
The code name of the architecture by which this silicon crystal is made isSandy Bridge.That is, this chip belongs to the second generation of architectureCore.Four computing modules include Intel Core i7-3820. Also in this case there is support for such an important technology as NT. With its help, these 4 physical processing modules program code and data at the logical level turns into 8 threads. In addition to this, this semiconductor chip supports 64-bit computing.
Frequencies
Dynamically adjust value clock frequency capable i7-3820. Characteristics it indicates support for technologyTurboBustand it is with its help that this chip can change the values of this parameter. The minimum frequency value in nominal mode is 3.6 GHz. In the highest load mode, this processor is capable of delivering 3.8 GHz. The frequency multiplier of this CPU is blocked and so-called overclocking in this case is only possible at the system bus frequency on a computer component such as a motherboard.
Technological process. Energy efficiency. Specifications regarding power consumption
According to standards that are outdated today technological process This silicon crystal was manufactured at 32 nm.For 2012, this technology for the production of semiconductor chips was the most advanced and it was with its use that the most advanced such solutions were produced. As a result, the energy efficiency of this CPU today is far from optimal. The thermal package is set at 130 W by the manufacturing company for Intel Core i7-3820. Working temperature should not exceed 66 0 C. In reality, in nominal mode, as a rule, the central processor in question consumes 95 W, and its temperature is in the range from 40 to 65 0 C. It is after increasing the clock frequency in combination with air cooling that the previously given values can be higher than usual.
If you significantly increase the CPU frequency (more than 4.5 GHz), then it is even possible to exceed emergency values. To prevent this from happening, it is recommended that you first system unit The computer must be equipped with a liquid nitrogen cooling system. This, of course, is quite expensive cooling, but in such a situation you certainly cannot do without it.
Cache memory. RAM subsystem
Equipped with 3-level cache memory i7-3820. Characteristics the first of them indicates thatits total size is 256 kb. It is divided into 4 equal parts of 64 kb each, which are physically tied to a specific program code processing unit. Also, these 64 kb are divided into 2 equal parts of 32 kb each. One of these parts is for storing code, and the second is for data. The total volume of the second level is 1 MB. Like the first level cache, it is divided into 4 equal parts of 256 KB, which can also exchange data with a specific computing core. The third level is common to the entire CPU and its size is 10 MB.
The key feature of this computing platform is that its processors are already equipped with a 4-channel controller random access memory. As a result, installing 4 2 GB modules instead of 2 4 GB modules allows you to increase the performance of the computer computing subsystem by 10-15 percent. The maximum amount of RAM that the solution in question can address is 64 GB. The chip manufacturer recommends using modules with frequencies of 1066, 1333 or even 1600 MHz in conjunction with it. You can also install higher speed levels (for example, with a frequency of 1866 MHz or even 2133 MHz), but heresignificantThere will certainly be no benefit from such a configuration for the reason that they will only operate at 1600 MHz, and this limitation comes from the BIOS system.
Overclocking
The chip frequency multiplier is locked in i7-3820. Overclocking like reThe result can be achieved in this case only by increasing the system bus frequency motherboard. This is not at all a standard solution for such a computer platform, in which almost all CPUs have an unlocked multiplier and their operating frequency can be increased without any problems. The fixed multiplier value for this silicon chip is 44. The maximum frequency value for this parameter is computer system, like the motherboard bus, can reach 133 MHz. Multiplying these two numbers together, we get 5.8 GHz. This is the maximum possible frequency value at which the solution in question can theoretically operate.
In reality, with air cooling on this CPU you can get 4.3-4.5 GHz. If we supplement the system liquid cooled, then it is quite possible to reach the level of 5.0-5.2 GHz. These are already excellent overclocking frequencies, which in reality allow you to get an additional 18-20 percent of performance.
Synthetic tests
Shows some of the best results Intel Core i7-3820 in synthetic tests. Moreover, in some cases it bypasses even more expensive solutions within this platform. For example, in test 3DMark2001SEthe hero of this article gives out54964 points. This is more thani7-3930K,which gives only 45801 points. But there is a completely logical explanation for this: the base frequency of the latter is only 3.2 GHz versus 3.6 GHz fori7-3820.
Another flagship chip, which in nominal mode is inferior to the processor in question, isi7-2600K.It produces a score of 52489 in this popular test suite. Again, the reason lies in the lower frequency - 3.4 GHz. The gap in this test becomes even greater when compared with AMD's flagship solutions. For example,FX-8120in normal mode at a frequency of 3.1 GHz it can only give 42321 points. After overclocking to 4.6 GHz, Intel processors give out about 68,000 points, but the AMD solution in a similar operating mode can only give out 45,586 points. That is, even after overclocking, the leading AMD CPU cannot catch up with the flagship solutions of its direct competitor,and it is for this reason that there is little point in comparing its leading processor with Intel solutions. The difference will be very, very significant.
Results in toys
As noted earlier, any gaming application can run without problems processor i7-3820 . And even with the highest possible settings. In this case, the number of frames will be sufficient for a comfortable game in any case. Results of real game tests in the gameBatmanversionsArkham Cityindicate that in nominal mode the processor in question can produce 50fpsin modeFullHDand high detail of the displayed image. After overclocking to 4.6 GHz the numberfpsincreases to 64. Moreover, by a similar amountfpsthis game can boast of more expensive processors, For example,i7-39 6 0K. Most likely, in this case there is already a limitation on the part of the software, which can only use 4 physical cores.
The situation in the game changes slightlyHitman: Absolution.In this case, the hero of this articlein a similar mode and with exactly the same detail is capable ofissue 78fps,and its more expensive brother - 84fps.After overclocking to the same 4.6 GHz, the situation changes, and the more expensive processor catches up without any problems i7-3820. Test shows that in both casesfpsis set at 93.Even greater valuesfpscan be obtained in a modern gaming simulator -F1 2012.In normal mode, this chip produces 122fps,its more productive and expensive brother - 132.
After overclocking to 4.6 GHz, this gap is reduced and amounts to 154, respectively.fpsAnd156 fps.All these results can be easily explained in terms of clock speed. The 3820 has a maximum value of 3.6 GHz, and the 3960 has a maximum value of 3.9 GHz. If the frequencies are equalized, then the performance of these chips is almost identical to most modern software. The difference can only arise when the code is optimized for 6 or even 8 physical cores. But so far there are quite a few such programs. And the process of switching to a larger number of computing modules has not yet become widespread enough. Computers with a CPU with more than 4 cores are still quite rare, and there is no particular point in such optimization at the moment.
Perhaps the situation will change with the release of a new platform from AMD, codenamed “AM4”. With its release, chips with 8 physical units for processing data and program code will appear in the segment of desktop systems. This should speed up the process of optimizing software for multi-core processors, but still this process will be extended over time.
Price
Two recommended prices are indicated on the official website of Intel for i7-3820. Price for configuration optionTRAILcorresponded to 294 dollars. A more advanced version of the configuration for this chip was priced by the manufacturer at $305. On the one hand, this is a fairly high cost, as for a central processor. But for the platformLGA2011 is one of the most affordable CPUs. Essentially, in this case it is budget solution. But at the same time, its computing capabilities are quite sufficient to process any program code, including the most demanding computer hardware resources.
Reviews. The future of this computer platform
It boasts truly impressive performance i7-3820. Reviews This is confirmed quite often. Any modern software on such a semiconductor chip will run without any problems. At the same time, it also has quite a large overclocking potential. It is also necessary to add to this that the CPU was released in 2012. That is, this computing solution, although it was released quite a long time ago by computer standards, still continues to be relevant and allows its owner to solve any problems at the moment. The disadvantages of this silicon crystal include the fact that it is manufactured according to the standards of a technological process that is outdated today, which corresponds to 32 nm. Accordingly, its energy efficiency is far from the best.
As noted earlier, this processor was intended to be installed in a socketLGA2011. Currently he has been replaced byLGA2011-v3,which supports the latest modifications of the most productive and most energy-efficient chips. As a result, this chip and its computing platform are outdated in terms of technical specifications and power consumption, but its performance still continues to be at an acceptable level and allows it to solve almost all possible problems, including the most demanding ones.
Results
Redundantthe level of performance for its time that was discussed in this material could boast i7-3820. It had 4 computing units, which, using proprietary technology from Intel, made it possible to obtain 8 threads of program code processing. This CPU was also equipped with an increased cache size and had a 4-channel RAM controller. As a result, its performance allows you to solve any problem without any problems. In addition, the capabilities of this CPU for exactly 3-4 years will be more than enough to run any applications, including the most demanding ones.
