The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. And it is clear that this is a server processor, on which no one will run games. Because this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a low game result, just 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 comparing not only were the equipped with different video cards and different amounts of RAM. 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. 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 resolution 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 i9-13900KF is more energy efficient than the EPYC 7643 since it has less power consumption: 125W vs. 225W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to know its TDP. It is necessary to calculate so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

Let's say you want to use the processor not only for gaming, but also for machine learning, streaming, programming, video editing or video rendering, then the main parameter for you is its performance in multi-threaded mode. In this mode, the processor uses all cores and threads that it has to the maximum to achieve maximum performance. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to make sure that the program that you are going to use on your computer can work in multi-threaded mode. Because there are still many programs that can use only one core to work, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most useful will be the the possibility of overclocking it and release date of the processor. The newer the processor, the longer it will last you. 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 continue to maintain maximum FPS even in new games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The economy are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i9-13900KF is 46% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 24 more core than Core i9-13900KF. 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 i9-13900KF is better: 18
The number of parameters for which AMD EPYC 7643 is better: 18
Although it should be realized that all the number in the text above do not mean that taking them into account you should entirely trust a simple quantitative comparison. Better to watch the testing video and read the opinion of of people who bought Intel Core i9-13900KF and AMD EPYC 7643 before making a selection which processor to buy for gaming and which not.
