As we all know, the Intel Core i9-9900K is the first consumer-grade i9 processor, and it has always been the strongest game CPU, but this situation has recently changed.

Intel released the new Intel Core i9-9900KS at the end of last month. As an official system, it is naturally the title of the most powerful game U from the Intel Core i9-9900K.

Intel Core i9-9900KS, with 8 core 16 thread design, base frequency 4.0GHz, full core maximum turbo frequency is 5.0GHz, triple slow 16MB, TDP 127W, maximum support 128GB DDR4 2666MHz dual channel memory, equipped with UHD 630 core display, The maximum dynamic frequency of the graphics card is 1.20GHz.


Intel Core i9-9900KS Compared with i9-9900K, the fundamental frequency has been increased from 3.6GHz to 4.0GHz in i9-9900K. The biggest difference is that the maximum core frequency of i9-9900K single core is 5.0GHz. The frequency is 4.7GHz, while the Intel Core i9-9900KS is very aggressive, with a maximum core frequency of 5.0GHz. Of course, the frequency has been greatly improved, and the TDP has been adjusted to 127W, which is 32W higher than the Intel Core i9-9900K.


The Intel Core i9-9900KS and i9-9900K core frequency mechanisms are shown below:


With such a powerful CPU, we naturally have to see its strength. The following is the test platform:


The first is the Cinebench rendering test, which tests both R15 and R20. The results are as follows:

R15 single-core score is 214cb, multi-core score is 2126cb;


The R20 single-core score is 517pts and the multi-core score is 5149pts.


V-RAY is also a common item for testing processor rendering performance. The Intel Core i9-9900KS has a final score of 13,969 points.


Next is the CPU-Z Benchmark, the Intel Core i9-9900KS score is single-threaded 587.6, multi-threaded 6020.5, multi-threaded magnification 10.25.


The Intel Core i9-9900KS chess test score is multi-threaded 34966, single-threaded 3899.



For the decompression speed of the Intel Core i9-9900KS, we tested it with WinRAR and 7zip, which has a lot of processor performance.

The Intel Core i9-9900KS has a single-thread speed of 2795KB/s and a multi-thread speed of 15308KB/s in the WinRAR test.



In 7zip, the Intel Core i9-9900KS single-threaded overall score is 7901 MIPS, and the multi-threaded overall score is 53826 MIPS.



We also performed a memory pre-cache test on the Intel Core i9-9900KS. The results are as follows:


Finally, the 3DMark test can reflect the game performance of the processor. We take the physical score and the processor score as the result.

  • Fire Strike has a physical score of 24,908 points;
  • Fire Strike Extreme has a physical score of 25028 points;
  • Fire Strike Ultra has a physical score of 24241 points;
  • Time Spy has a processor score of 10592 points;
  • Time Spy Extreme has a processor score of 5062.

In terms of finishing, each test run score of the Intel Core i9-9900KS is 2% to 13% higher than the Intel Core i9-9900K. It should be said that the frequency and TDP upgrade are basically reflected in the score, if there is better If the heat dissipation condition and the stability are controlled better, the theoretical performance improvement will be much higher.

The Intel Core i9-9900KS package contains the i9-9900K special edition, which is a batch of processors with good quality and pre-overclocking. So, since the system is better than the average Intel Core i9-9900K, the overclocking potential will be better, or the performance has been fully developed, let us try.

After many attempts, the voltage was 1.38V, and the P95 oven was successfully tested at a full-core 5.2GHz frequency. The highest frequency through the R20 is 5.4GHz for the whole core, and the highest boot frequency is 5.5GHz for the whole core, but it cannot be tested by running or baking.

After overclocking to the full-core 5.2GHz, I would like to test the scores. Before the overclocking, the performance improvement is limited, and the increase is roughly 1% to 5%.

But as the voltage increases, the heat dissipation pressure will also become larger. The 360-in-one water-cooling we used this time can’t hold the violent behemoth. The heat and performance are flying together. After hitting the temperature wall, the frequency is reduced to the full core 4.7. At GHz, the temperature will gradually reach around 90 °C.

So we came to the conclusion that the Intel Core i9-9900KS is better than the i9-9900K. Under the condition of the frequency, the power consumption of the same platform is lower than that of the Intel Core i9-9900K overclocked to the full-core 5.0GHz. The full-core core frequency to 5.0GHz is already an officially set frequency that is more balanced in all aspects. The significance of manually overclocking again is not great.
