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 run games. Because this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a little game result, just look at the FPS that it produces in real games in the summary table below.
List of other games in which processors were compared: NBA 2K20, DOTA 2A, The Witcher 3: Wild Hunt, Shadow of the Tomb Raider, Monster Hunter World, Counter-Strike: Global Offensive (CS GO), Microsoft Flight Simulator, Half-Life: Alyx, Forza Horizon 4, PlayerUnknown's Battlegrounds (PUBG), Resident Evil 7 Biohazard, Control, League of Legends (LOL), Ghostrunner, Horizon Zero Dawn, Hitman 3, Metro Exodus, Battlefield V.

Valheim	129.2	116.7

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 tested computers not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: FullHD, 2K or 4K. 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.

Software benchmarks

If you want to use the processor not only for gaming, but also for machine learning, programming, video rendering or video editing, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum performance, the CPU includes all cores and threads that it has. You will find out 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. Since 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 most helpful will be the the possibility of overclocking it and release date of the processor. 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 can be said about overclocking. When the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS even in the newest games. The savings are obvious! It turns out that you do not 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 EPYC 7643 is 4% better than EPYC 7552 in terms of CPU frequency. 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 EPYC 7552 is better: 21
The number of parameters for which AMD EPYC 7643 is better: 8
However, it should be understood that all the figures that you have looked at here 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 AMD EPYC 7552 and AMD EPYC 7643 before making a selection which CPU to buy for gaming and which not.
