The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. And of course, this is a server processor, on which no one will play games. Because this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a small game result, just look at the FPS that it produces in real games in the summary 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 participating in the comparisons not only were the equipped with different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, FullHD or 4K. So 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 compare it in one assembly with the video card that is installed in your computer.

To make a finishing choice on which processor is better, you should also consider the generation of its core. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Core i9-9900KS is more energy efficient than the Core i9-9820X since it has less power consumption: 165W vs. 127W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to 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

For example you plan to use the processor not only for gaming, but also for programming, streaming, machine learning, video editing or video rendering, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU includes all threads and cores that it has to the maximum to achieve maximum efficiency. You will find out this data from the benchmark tables below. Before using the data from these tests, be sure to find out whether the software that you are going to use on your computer can work in multi-threaded mode. Because there are still many programs that use only one core to work, and all the benefit 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 useful. The later the processor is released, the longer it will last you. And the easier it will be to upgrade the system in the future. The same benefits from the presence of overclocking. If the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS even in new games. The savings 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 i9-9820X in terms of CPU frequency. Another difference is that Core i9-9820X 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 i9-9820X is better: 19
The number of parameters for which Intel Core i9-9900KS is better: 10
However, it should be realized that all the data that you have looked at here do not mean that taking them into account you should entirely trust a simple comparison of these figures. Better to watch the video tests and read the reviews of real owners of Intel Core i9-9820X and Intel Core i9-9900KS before making a choice which processor to buy for gaming and which not.
