[PConline evaluation] As long as there is a little attention to the DIY hardware, we all know what the "love wife" is talking about, "love wife" that is through i7, are all due to similar harmonic. The "beautiful wife" this beautiful nickname has been almost 10 years since the birth of the Core i7, and from time to time it will be seen that someone has come up with jealousy because in the hearts of players, the i7 has been the "most powerful CPU" for nearly a decade. Title hooks.
However, from the beginning of this year, the era of i7 king is over, and it is Core i9! That's right, Intel has named their highest-end, hottest CPU as the Core i9. Core i9 belongs to the Skylake-X in the Core X family and it is a continuation of the flagship CPUs of Sandy Bridge-E, Ivy-Bridge-E, Haswell-E, and Broadwell-E. Of course, the previous flagship model is called i7, and only the new Skylake-X will use the new Core i9 title!
To some extent, you can think that the appearance of Core i9 is just a digital game played by Intel, but it is undeniable that such a naming technique can better tell the user which is the high end and which is the fever, it is undoubtedly right. Rebranding of the Core brand image.
Since the beginning of 2008, Intel has built Core i's grading method for Core Duo. Whether you are on a quad-core or eight-thread on a mainstream platform or ten core and twenty threads on a fever platform, they are collectively referred to as Core. I7 With the trend of multi-core, this general naming approach clearly does not clearly and accurately tell the user what level of i7 you choose. Therefore, it is also necessary to set up a fever-class CPU alone to establish a “strandâ€.
Before we evaluate the Core i9-7900X, we have conducted a detailed evaluation of another Core i7-7820X in Skylake-X. There is a detailed introduction to the Core X family, and interested users can click I9 is ​​stronger than it, 8 cores are fully on 4.3GHz! i7-7820X first test to come to know new.
Specifications: 10 core 20 threads can only be regarded as low-level i9! ?
At the Taipei Computer Show conference, Intel had already said that the specification of the 18-core 36-thread is the complete body of the i9. The Core i9-7900X we got this time is the "low-grade version" of the i9 series. That is to say, 10 core 20 threads are just the lowest version of the i9. In the future, there will be higher specification models of 12, 14, 16, and 18 cores that will be on the market in succession. No sign).
Obviously this Core i9 release is Intel's multi-core monster for enthusiasts who are seeking multi-threaded applications. In addition to the specifications of the number of core threads, the significant increase in the frequency of the CPU is one of the hallmarks of this generation.
Number of pins and foolproof: LGA2011 upgraded to LGA2066
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 here. The more extreme core processors with better cooling requirements, really should use better thermal brazing.
PCIe channel number:
The current CPU on the X299 platform, all i9 have 44 PCIe 3.0 channels, the remaining i7 ~ i5 are only 16 to 28, 44 have nothing to say, law-abiding upgrade (the previous generation 6900K, 6950X are Is 40, more than 4 let you add a M.2 interface or USB 3.1 it).
CPU-Z
The core and frequency point of view, in fact, has been very awesome, ordinary Turbo can reach 4.3GHz, Turbo Boost Max 3.0 acceleration technology can make a small part of the CPU core speed up to 4.5GHz, 13.75MB L3 cache number is also a comparison In particular, although it is less than half of the 25MB of the previous generation 6950X, due to the fact that the data call logic of the new architecture is not the same, in fact, even if the three are slower, the performance improvement is still very impressive. Can refer to i7-7820X (three slow 11MB) and i7-6900K (three slow 20MB) comparison, 7820X is still much stronger than the 6900K.
Detailed comparison of parameters:

Compared with the previous i7-6950X with 10 cores and 20 threads, the four-channel memory frequency has been increased to 2666MHz. The above three have also been commented on, and the most important is that the CPU frequency is greatly improved. This is for the actual performance. The effect is very large (if you do not trigger the high temperature protection downshift). The TDP is still maintained at 140W. For such a large increase in frequency, TPD can also be pressed at this value, which is not easy.
The current price of 7499 yuan
The listed price is 7,499 yuan, which is expensive. However, if you look at it in comparison, it seems that it has already been a lot cheaper. Need to know that the previous generation of 10 core 20 thread i7-6950X pricing in the 13,000 or so, now as long as 7499 yuan, it can be regarded as Intel finally renewed the generation of it.
Theoretical performance test:
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.
The main board used in this test was the Gigabyte X299 AORUS GAMING 3. It was a good choice for the first X299 motherboards to be listed. Anyway, GAMING 3 has always been recommended by the Beastmaster.
Gigabyte's GAMING series motherboards have always been named and positioned by GAMING plus numbers. For example, GAMING 9 is its top model, and GAMING 3 is a model for positioning cost-effective models.
Gigabyte AORUS X299-GAMING 3 motherboards use black and gray main colors, but the CPU power supply module, PCIe slot and the South Bridge's carved LOGO are all made of LED lights, so that the original monotonous black and gray with some embellishment.

wPrime
Theoretical performance test summary: Fritz Chess, wPrime, CPU-Z are excellent software for testing multi-threaded performance, are purely theoretical calculations, the sensitivity of the thread is very high, so in the wPrime and CPU-Z test, 7900X The advantages of 10 core 20 threads and high frequency are very obvious, and it directly exceeds the previous generation flagship 6950X. Scores are not commented on one by one, and all are visually observable.
â— 3DMark physical operation test
Physical performance test summary: 3DMark series can fully tap the potential of CPU, has become an important indicator to consider the performance of the whole machine, we choose the physical computing part of which to test, simply compare the CPU performance. The 7900X score under silent frequency is 119% of the previous generation flagship 6950X, which is also about 10% stronger than the 7820X, which is in line with this core number gap ratio.
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

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!
Test summary: CPU performance, 7900X all-round leader in the previous generation of the 6950X, and the leading range is not small, the most obvious is the TMPGEnc software, the leading margin of nearly 50%, not to mention the Ruilong R7 1800X (after all Rui Dragon is much cheaper).
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
Summary of game performance tests: Through comparison, you can see that the performance of a single-player game running on a top-level CPU is not too different, and the 6500X wins or loses. The fundamental reason is that mainstream games on the market are not optimized for multi-core CPUs. , We have also tested before, as long as the number of threads after more than six, and then increase the impact of the thread on the vast majority of games are not too great. And, for the game frame rate, the GPU upgrade is significantly more than the CPU upgrade. So, if your needs are just playing games, I7-7700K is recommended. This is the game god U.
â— Platform power consumption comparison test
The standby power consumption i7-7900X is even a little lower than the i7-6950X, although this is absolutely negligible for a desktop platform. After the Prime95 is fully loaded, the power consumption of the i7-7900X has skyrocketed and is much higher than the 6950X. The fundamental reason is still related to the frequency. After all, although the boosting of the i7-7900X can bring about a significant increase in performance, the power consumption at full load is also huge. The same conclusion can be reached by comparing the 8-core i7-7820X with the 10-core i7-6950X.
â— Comparison of CPU full load temperature
Overclocking three wind frozen black gold version
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, 36 °C, but once fully loaded, the maximum temperature can go straight to 104 °C, after overclocking is reached 110 °C, it is still quite hot, but before foreign media also said that this generation X299 Extreme CPU Because of the three major reasons for the voltage controller, frequency boost, and internal use of grease, the overall temperature is higher than that of the previous generation. Therefore, please do not spray brazing on Intel. At the same time, it is also recommended that you use more heat dissipation performance. Good high-end water-cooled pressure this generation of CPU.
Additional simple overclocking test:
Do not adjust other parameters, only change the multiplier to 48 times, normal access to the system, running points.
4.8GHz
Overclocking summary: i7-7900X default frequency is 3.6 ~ 4.3GHz, Turbo 3.0 can accelerate up to 4.5GHz, i7-7900X own frequency is relatively high, so want to get more performance improvements through overclocking is not easy , 10 core performance overclocking 4.8GHz after a 9% performance increase. Calculate a sum, CPU price is 7499 yuan, 7499*0.09=674 yuan, that is equivalent to earn about 674 yuan after overclocking, this kind of algorithm is unreasonable to have a matter of opinion.
PConline evaluation room summary:
The overall performance comparison is as above, compared with the previous generation i7-6950X promotion rate is also 18%, but the price is far lower than the 6950X, so this generation can not say squeeze toothpaste, it is still worthy of recognition. However, if it is cost-effective, the CPU of the supreme class should not mention any cost.
PConline CPU ladder diagram -
Location is very clear, stronger than i7-7820X, so it is placed in the top position. And the current higher-end 12-core ~ ​​18-core i9 has not yet officially listed, the world has not even sneaked information, so this i9-7900X is the current Intel consumer-grade CPU is correct - more accurate statement should be The most powerful CPU with multithreading.
The evaluation finished running, anyway, compared with the previous generation of their own home products, this generation of promotion is still very conscience, the same price you can buy more core number of CPU, multi-threaded performance enhancement is super obvious. And support for the X299 motherboard can have a richer interface, it can be considered better than nothing.
As for AMD, for the moment, there are no 10 core products to hit the ring, thread tearing is said to be released in August, when there will be 10 core ~ ​​16 nuclear products listed, and Intel's 18 nuclear i9 estimates Will wait for AMD to move at that time.
