For the maximum in this test, the results of the most powerful processor in the site database are taken. And of course, this is a server processor, on which no one will run games. Because the cost of this processor reaches several tens of thousands of dollars. Therefore, if you think that the selected CPU has a little game result, look at the FPS that it produces in real games in the final table below.

The numbers in this table indicate the maximum FPS that was received on the device with the corresponding processor. Depending on the configuration of the computer (RAM size and Video Card) and graphics quality settings (Ultra, Medium, Normal), the results may differ quite significantly. We recommend that you better study the results of the Cinebench, GeekBench and Passmark becnmarks.
The computers that were in the comparisons not only did they have different video cards and different amounts of RAM. But users also tested them at different screen resolutions: 2K, 4K or FullHD. Therefore, the game benchmark data is approximate. But all video cards met the average system requirements of games. You will get more accurate information about how powerful the processor will be in games, if you get acquainted with the benchmarks that are made with the same video card that is installed in your computer.

To make a final choice on which processor is better, you should also consider the generation of its core. It is clear that the newer the generation, the better the performance of the processor in games and benchmarks, as well as its energy efficiency. In this case the Core i9-9900KS is more energy efficient than the Core i9-7900X as it consumes less power: 127W vs. 140W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, you must know its TDP. You need to buy a cooler that has the TDP data specified in the specification was greater than the TDP of the compared processor.

Software benchmarks

If you plan to use the processor not only for gaming, but also for video editing or video rendering, streaming, programming, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, the processor includes all cores and threads that it has to the maximum to reach maximum efficiency. You will find out this data from the benchmark tables below. Before using the data from these tests, be sure to make sure that the software that you are going to use on your computer can work in multi-threaded mode. Since there are still many programs that use only one core to run, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most helpful. The newer the processor, the longer it will last in your computer. And the easier it will be to upgrade the system later. The same can be said about overclocking. If the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS even in the newest games. The economy are obvious! Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer.

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i9-9900KS is 17% better than Core i9-7900X in terms of CPU frequency. Another difference is that Core i9-7900X has 2 more core than Core i9-9900KS. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which Intel Core i9-9900KS is better: 12
The number of parameters for which Intel Core i9-7900X is better: 19
However, it should be understood that all the data in the article above do not mean that you should be guided entirely by them and trust a simple quantitative comparison. Better to watch the video tests and read the reviews of real owners of Intel Core i9-9900KS and Intel Core i9-7900X before deciding which CPU to buy for gaming and which not.
