[PConline initial evaluation] Although the mouth does not say, but the body is very honest! This is the author's summary of Intel's "doing" this year. At this year's Taipei Computer Show, Intel released the latest generation of Skylake-X and Kaby-X Extreme Edition processors, "the highest 18 core 36 threads, a total of 9 models, the top is no longer a Core i7, but the Core i9, an unprecedented price of 1999 dollars. "And so on, a series of information all indicate that this year's Intel wants to defend itself as a dominant player in the high-end market." Who touched Intel's nerves? No name is known to everyone as a good thing for AMD.
Although Intel officials have been “professing†that the launch of the 18-core has always been within the plan and has nothing to do with the rival AMD's competition, the outside world has always been posed as a king of despise, but all the signs indicate that these are facades. In fact, Intel is indeed anxious. So today we have this flagship CPU test that is ahead of schedule!
Intel i7-7820X Reference Price: Loading... Image Reviews Quote Parameter Overview
18 core Core i9 squeeze really thanks to AMDPlease allow us to jump back to the release of Intel's 7th generation Core and AMD Ruilong at the beginning of this year. In January, Intel habitually released the third-generation 14nm Kabylake processor, in addition to the new processor. No bright spots. Two months later, AMD released the long-awaited Ryzen Ryzen. Relying on the multi-core, cost-effectiveness, and greatly improved single-core performance, it regained confidence in the market. Although it failed to exceed but is enough to attract Intel's attention, Intel’s PR is Under pressure to make mistakes...
Even more frightening is that AMD not only has Ruilong Ryzen, but also prepares a 16-core 32-thread Threadripper (linear translator) enthusiast processor built on the X399 platform, comparing Intel's existing X99 and the new X299 platform specifications. Not at all false. If Intel still upgrades the Extreme Edition processor according to the same "2C4T" upgrade, the 12-core Core i7 will not compete with AMD's 16-core processors. In order to avoid the reoccurrence of the performance throne history, for security purposes, it is also necessary to put out an 18-core to destroy your 16-core, and Core i7 also upgraded to Core i9 to demonstrate the supreme status.
It can be said that if AMD does not have 16 nuclear and X399 ready, Intel will definitely not have 18 nuclear Core i9's counterattack! Do not believe? You can see that none of the domestic media's first tests are Core i9. Although there are 10 core Core i9-7900Xs in the first release, it is difficult for you to doubt that Core i9 is not within the original plan. Even if the ten high-frequency nucleus completes the upgrade task, it is only the B plan adopted in the face of AMD's challenge. Of course, according to Intel's large-scale companies, there are technical reserves, which are used on the server, but it takes a little time to optimize the frequency. Otherwise, Core i9 with more than 12 cores will not be required to wait until next year. Only there.
In addition, according to the author's understanding of the new processor release time is also a lot of advance, the original plan was released in August/September, the previous time is the case, but this year Intel chose another May Taipei Computer Show released on the one hand, Taipei Computer Show is the focus of global PC players, on the other hand, in order to face AMD, Intel's mentality is evident.
There are advance publishing benefits ahead of schedule, but the original plan will not be able to keep up with the existing changes. The promotion of the new processor will surely be affected. June 19 lifted the ban, but one week before the lifting of the ban, Intel China has not yet received evaluation samples from the US headquarters. What's more, it is a domestic media. Therefore, this time the domestic can get the CPU to evaluate the media for the first time is very rare, not to pick three.
Our PConline's first test was an 8-core 16-thread Core i7-7820X, which belongs to the Skylake-X series. What position does it have in the entire Core X Extreme Edition family? Please continue to look at the introduction of this generation of Intel Core X family.
Intel Fever Core X Family IntroductionThis generation of Intel Core X lineup is very powerful, more than the number of processors released in each generation of the Extreme Edition. No wonder the netizens all jokingly called this generation of toothpaste more crowded, in terms of the number of processors. In the entire Extreme Edition system, it is divided into Skylake-X and Kabylake-X two series, a total of nine models, of which seven belong to Skylake-X, all are more than six core specifications, but are divided into two Die packages, among which The following 12 cores are LCC (Low Core Count), 12 cores or more are HCCs ((High Core Count), from Core i7 to Core i9, the number of PCIe channels is 28-44, TDP starts from 140W; the other two are Belong to Kabylake-X, all 4 core specifications, Core i7 is 4 cores and 8 threads, Core i5 is 4 cores and 4 threads, PCIe channel number is only 16, TDP 112W.
The Core i7-7820X we got from PConline is the first player in the Core i7, 14nm process, 8-core 16-thread specification, 3.6GHz-4.5GHz frequency, 11MB L3 cache, DDR4-2666Mhz memory support, LGA2066 interface, 28 PCIe channel, TDP 140W, official price $ 599. Is such a specification worthy of such a price? The following will analyze for you alone, just look below.
In general, Intel has a dimension expansion in this generation of Core X, the highest end is no longer played by the Core i7, and is pushed up to the new Core i9, while the top-level Extreme Edition is put down to the 4-core Core i5. Yes, to a certain extent, Intel is further refining the product line of the fever version to better meet the different levels of players. It can also handle the different specifications of the AMD 8/6 core specifications of the Ruilong and future Threadripper. Device. However, the extreme version of the 4 Core i5/i7 and the mainstream Core i5/i7 seriously overlap, to be promoted, is bound to cause many players to choose difficult. If you choose a low-key, then the five-generation Core Broadwell's embarrassing again, Kabylake-X always escape the fate of passers-by A.
Interface upgrade LGA2066 requires new X299 motherboard support
The new X299 motherboard was also released at the Taipei Computer Show, replacing the original X99 motherboard as a new generation of Extreme Edition processor. In this evaluation, we will use the ASUS Prime X299-DELUXE motherboard as a evaluation board. If you want to learn more about the technical explanations of the X299, you can click the link below to jump to the motherboard first page.
ASUS's PRIME series X299-DELUXE motherboard, color continuation of Durex style are all pure white tone show people, in the middle of the motherboard integrates a black and white OLED display, this screen can not only show the current CPU temperature, but also can display the CPU The voltage, as well as the error of the motherboard, etc., is more direct than the traditional digital code error, and is convenient for troubleshooting various unknown conditions encountered in the first test.
CPU appearance and opening: mysterious black spots and cheap silicone grease
Because the interface has changed, it is no longer the LGA 2011 interface on the X99 platform. Therefore, the position of the foolproof port on both the upper and lower sides of the CPU also changes. In addition, the wings on the four corners of the CPU have also changed, including the lower left wing There is a corner, but a similar RFID/NFC near field identification tag, in Intel's official database, there is no explanation of any details of this change, so the specific role is reserved for Intel's official explanation to know.
But what is certain is that this raised "small black spot" makes the difficulty of opening the lid of the CPU! what? Intel Extreme CPU can open cover? Yes, there is a thick layer of black glue from the edge of the CPU cover and the PCB. You can probably guess that the internal heat sink material is silicon grease instead of brazing material. This is confirmed by the fact that it is indeed silicone grease rather than brazing. Intel thoroughly learned that the Extreme Edition processor is not willing to use brazing instead of using cheap silicone grease.
The impact of cheap silicone grease on overclocking There is no need for the author to go into details, and the core number is even more. How does the extreme version of the processor with higher heat dissipation effect after using low-cost silicone grease have an impact on overclocking? Overclocking test will be answered for everyone. In fact, Intel's trick is not only this point, but also the distribution of the number of PCIe channels.
Reduce the number of PCIe channels! Don’t think that we don’t notice
Tucao is cheap silicone grease, I have to Tucao about the PCIe channel and the three-level cache shrink. Take the Core i7-7820X as an example. There are only 28 PCIe channels. Compared with the previous generation of the same number of core threads, the Core i7-6900K has 40 PCIe channels. The previous generation has 12 more than the newest ones! The original 16x+16x+x8 allocation scheme can now only shrink to 8x+8x+4x+ (4x+4x), and enthusiasts are looking for full-speed SLI and RAID 0 arrays. Other models such as: Kabylake-X's Core i7/i5 PCIe channel number is only 16, directly like the mainstream Core i7/i5, enthusiast-level players will certainly not buy this account, this is why the author has not been optimistic about Kabylake-X is one of the reasons.
On the third-level cache, the Core i7-6900K is 20MB, while the Core i7-7820X is only 11MB. The L3 cache of the 8-core i7-7820X is reduced from the previous i7-6900K's 2MB per core to 1.375MB. This value is not too high. Conforms to the previous integer rule, so 11MB is so strange. The reduction in the number of PCIe channels and the reason for the shrinking of the third-level cache must be explained by saying that the i7-7820X is half as cheap as the i7-6900K. Intel's logical thinking is no problem.
Tucao finished, let's take a look at this 8-core 16-thread Core i7-7820X other detailed parameters:
2.0: 4.3GHz 3.7GHz 4.0GHz L3 cache 11MB 20MB 16MB memory support DDR4-2666
(four channels) DDR4-2400
(four channels) DDR4-2400
(Dual Channels) Set Display None No Turbo 3.0/XFR Support Not Supported Support Price $599 $1099 $499 TDP 140W 140W 95W
The biggest point of view is that the Core i7-7820X can be tuned to a higher frequency, the highest Turbo frequency can reach 4.5GHz, and the memory frequency support can be increased to DDR4-2666MHz. The TDP still remains unchanged at 140W. Information players are most concerned about the price, the official price of 599 US dollars, the domestic mainstream is about 4499RMB.
CPU technology introduction! Suitable for technology house you1: Turbo Boost MAX 3.0 technology, this technology is in fact quite similar to AMD XFR technology, both in the case of cooling conditions can be in the original Core frequency 2.0 based on the increase in the frequency of 0.1 ~ 02GHz, or better The performance is improved, so you will see the frequency of the 7820X on the above table will be Boost 2.0: 4.3GHz and Boost 3.0: 4.5GHz. There are currently 6950X, 6800K, 6850K, 6900K, 7900X, 7820X, and E5 1600V4 series that support this technology, and it is stipulated that it can be executed on 64-bit systems and not on 32-bit systems.
2: Skylake-X supports AVX-512 instruction set. Desktop CPUs including 7-core Core Kaby Lake processors and server-class Xeon E3 v6 series also support AVX 2.0 instruction set at most. AVX-512 is a new generation. In the instruction set, the vector bit width is increased from 256 bits of AVX 2 to 512 bits. Floating-point and integer performance is twice as strong as AVX 2, in particular, the computational speed of some functions of the basic math library, especially the linear algebra library, is doubled. AVX512 is an extension of the SIMD instruction set, and programs that call SIMD can benefit from it.
Intel's push AVX-512 instruction set was originally used for Xeon Phi, Xeon E5/E7 and other high-performance server processors and accelerator cards. It is of little significance in the consumer market. Earlier there were rumors that Intel would cut off consumption. The processor AVX-512 instruction set support, now look at Intel finally did not start, retain this feature.
3: For the problem of shrinking the L3 cache of some models, Intel’s technology is explained in this way: The new generation of Skylake-X CPU cache structure is adjusted to compress all core shared L3 caches. The space is allocated to each core L2 cache, making the size of the original L2 cache directly expand from the original 256KB to 1MB, this will improve the cache hit rate, so that the IPC number of the overall process will be compared with the non-fever location of Skylake-S A slight increase. .
This evaluation mainly from the CPU theoretical performance, game performance, power consumption, temperature comparison, overclocking five aspects, in the CPU performance evaluation, we added a variety of competing products CPU as a comparison. CPU game performance test with NV GTX1080Ti graphics card to ensure that the graphics card does not become a CPU bottleneck.

â— CPU theoretical performance test
Fritz Chess Benchmark is a computer chess force test program that comes with chess software. Because it supports CPU multithreading, and it does a lot of scientific calculations, it is often used to test the scientific computing capabilities of computers. It uses the algorithm of AI to think about chess's algorithm. To test the computer's ability to run chess, the higher the score, the stronger the performance.
wPrime is a software (especially a parallel capability) that tests the computing power of a computer by calculating the number of primes. The shorter the time, the better the computing performance.
CPU-Z is a well-known CPU detection software. It is a software that detects the highest degree of CPU usage. The supported CPU types are quite comprehensive. The software's startup speed and detection speed are very fast. In addition, its new Benchmark can effectively test the single-core and multi-core CPU performance. The higher the score, the better the performance!
â— 3DMark series physical operation test
â— Common software performance testing
WinRAR is a powerful compressed package manager, which uses its equal size file for compression time testing, which can effectively detect the performance of the CPU. The less time, the better the performance.
â— Professional software performance test
TMPGEnc is a set of old high-quality video code conversion tools developed by Japanese companies. Expert group with more than 15 years of video conversion and editing software experience. The ability to perform format conversion and encoding software on its peer-to-peer capacity video files can effectively test CPU performance. The less time spent, the better the performance!
CineBench is a persuasive set of CPU and graphics test systems. The latest is the R15 version can support up to 256 logic cores, and also enhanced the investigation of shaders, anti-aliasing, shadows, lights, and reflection blur, for CPU performance. The detection is more accurate, the higher the score, the stronger the performance!
Using Adobe Premiere Pro to transcode and export the same video file can effectively test the CPU's encoding capabilities, and the less time it takes, the better the performance.
Test summary: CPU theory runs on points, the 7820X can lead the previous generation of the 6900K, compared to the Ruilong R7 1800X is also the case, in the 3DMark physical running points and wPrime parallel computing on the 7820X leading margin is relatively large, only on the CPU-Z It is a weak lead.
In actual software applications, the multimedia processing capability is outstanding, and the Pr video output, video conversion, and rendering capabilities are all relatively strong. The advantages are more obvious than the theoretical running points. This just reflects the optimization and improvement of the new processor in the architecture.
â—CPU game performance test
Test summary: All games in the game test were run at a resolution of 2K. Among the 6 games, there were 4 games. The number of frames tested was very close. Only GTA5 and singularity were reflected in the gap. The 7820X on the GTA5 leads the Ruilong R7 1800X with 15 frames. The singularity gap is more exaggerated, and the CPU frame rate score is only 70. Clearly, game optimization is not yet in place. However, the 7820X has a 7-frame advantage over the 6900K.
â— Platform power consumption comparison test
Test summary: In the power consumption test, the 7820X is only 71W standby. At this time, the energy-saving features on the Asus X299 motherboard play its role, and some of the instantaneous frequency drops further to only between 800-1200MHz. The comparison also turns on the default energy-saving X99 platform. The standby power consumption of the 6900K and 6800K is lower. When the power is full, the power consumption of the 7820X directly rises to 238W, which is why the power consumption of the CPU is the highest. This can be understood as the higher power consumption of the 7820X. The power consumption of the 7820X on the game is comparable to that of the 6900K.
Comparing the TDP with only 95W Ruilong R7 1800X, the 7820X has a little higher than the opponent regardless of standby or full load.
â— Comparison of CPU full load temperature
CPU full load temperature test We used a high-end radiator product: overclocking three wind freeze black gold version (5 heat pipe) radiator to test.
Test summary: Standby temperature is also good, 30 + °C, but once fully loaded, the maximum temperature can go straight to 104 °C, even after overclocking reaches 110 °C, silicone grease ~ grease grease ~ I also brazing.
Additional test: What happens after overclocking?Before the overclocking test, I saw a foreign overclocking player will i7-7900X 1.25V OC4.7GHz, physical quality is quite good, but I get 7820X is not a big Eagle, the voltage can be 1.28V can OC4.8GHz, but only After starting up, the test can't go through. Finally it needs to be pressurized to 1.35V to stabilize all the tests.
Overclocking summary: i7-7820X default frequency is 3.6GHz, air-cooled conditions can be all 8 core overclocked to 4.8GHz, overclocking rate of 33%! What is the concept of this? Compared with rivals, the same 8-core R7 1800 air-cooled overclocking is about 4.1GHz or so has been the limit, compared with their own, the previous generation of i7-6900K air-cooled is generally 4.3GHz level, this shows that this generation Skylake-X's overclocking potential is relatively large. I believe that the overclocking capability of the i7-7820X will be further liberated when the lid is opened and water cooling is added.
In terms of performance improvement after overclocking, due to Turbo Boost 2.0 and 3.0 acceleration, the performance of the i7-7820X itself has been increased, but the performance of the 8-core 4.8 GHz overclocking is still 9%.
The effect of different memory frequencies on the memory bandwidth of the X299 platform:
Using AIDIA 64's own memory bandwidth test tool to test each frequency bandwidth of the two platforms, the test memory is using GSkill TridentZ RGB DDR4 3200 8GBx4 C16.
It can be seen that in the memory control of the new generation of Skylake-X, the higher the memory frequency, the faster the read speed of memory is larger than that of the previous-generation Broadwell-E. However, the improvement in writing has been minimal, and even the speed of writing has not been as high as that of the previous generation.
PConline evaluation room summary:
Combined with all the above CPU test results, the 8-core 7820X lead is also about 8-core 6900K about 14%, leading the opponent's current strongest 8-core Ruilong R7 1800X is also 21%, so to speak: If AMD does not have 16 Nuclear Threadripper to "teach people", this i7-7820X can be said that this "post-i7 era" in the strongest i7, 8 core default can be simultaneously Turbo to 4.3HGz! PK Ruilong R7 is like a dog.
According to 3DMark's physics results, the new 8-core i7-7820X actually exceeds the previous-generation 10-core i7-6950X. Even if the CPU specification is less than 2 cores, it still relies on the improvement of the architecture and higher frequency to make it in 3DMark. Get better results (data comparison based on the existing 6950X results), so the CPU ladder diagram position above i7-6950X, I am afraid that only the Core i9 can currently rank in front of it.
â—PConline evaluation room summary:
1 Performance: Directly kill AMD's current strongest Ruilong R7 1800X, 21% of the overall performance leading competitors, but also beyond their own previous generation of 10 core i7-6950X, in a large degree of multimedia encoding and rendering capabilities Improve is currently the strongest Core i7. The only fly in the ointment is the castration of PCIe channels. Fortunately, the shrinking of L3 cache has no obvious effect on performance.
2 market positioning and price: 599 US dollars (domestic 4499RMB) is about half the price of the previous generation of 6900K, but with greater performance, success is not a problem. Contrast to rivals, although Rui expensive 100 US dollars, converted to the domestic difference is also 800 yuan, for the difference between high-end CPU is actually not too much, I believe more enthusiasts will consider this i7. The overall platform price, be regarded as the new X299 motherboard and four memory, the maximum platform price difference may be around 2000, whether to pay for this 21% performance? It depends on your personal choice.
In terms of positioning, although this is the strongest Core i7, it is by no means Intel's strongest CPU. It is only temporarily able to hang AMD's family. However, AMD will soon have a counter-attack, and it will be a good match for Rui Long, but what about the more core Threadripper?
3 power consumption: not many bright spots, quite satisfactory, the temperature ... Intel you learn bad.
In fact, this Corei7-7820X is just a starter, really used to protect the performance of the throne is 18 Core i9 ... ... continue to focus on PConline for everyone to bring the Core i9 first test
