For the maximum in this test, the results of the most powerful processor in the site database are taken. And it is clear that 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. And if it seems to you that the selected CPU has a small 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 participating in the comparisons not only were the equipped with 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. To be sure exactly how much performance 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 final decision 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 i9-9900KF is more energy efficient than the Ryzen 9 7900X since it has less power consumption: 170W vs. 95W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to know its TDP. It is necessary to count so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

If you plan to use the processor not only for gaming, but also for streaming, video editing or video rendering, machine learning, programming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU includes all cores and threads that it has to the maximum to reach maximum efficiency. You will learn this data from the benchmark tables below. Before you take into account the data from these tests, be sure to check whether the software you are going to use on your computer supports multi-threaded mode. Because there are still many programs that can use only one core to run, and all the advantages of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most helpful. The later the processor is released, the longer it will last in your computer. And the easier it will be to upgrade the system later. The same benefits from the presence of overclocking. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS even in new games. The savings are obvious! Accordingly, you do not need to buy a new CPU to enjoy the games any longer.

Another difference is that Ryzen 9 7900X has 4 more core than Core i9-9900KF. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which AMD Ryzen 9 7900X is better: 33
The number of parameters for which Intel Core i9-9900KF is better: 5
However, it should be realized that all the number that you have looked at here do not mean that taking them into account you should entirely trust a simple comparison of these numbers. Be sure to watch the testing video and read the opinion of real owners of AMD Ryzen 9 7900X and Intel Core i9-9900KF before making a choice which of the CPUs to buy for gaming.
