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.
List of less popular games in which processors were compared: Metro Exodus, Hitman 3, Ghostrunner, Microsoft Flight Simulator, Control, Shadow of the Tomb Raider, Counter-Strike: Global Offensive (CS GO), NBA 2K20, The Witcher 3: Wild Hunt, DOTA 2A, Half-Life: Alyx, Forza Horizon 4, Battlefield V, Monster Hunter World, League of Legends (LOL), Resident Evil 7 Biohazard, PlayerUnknown's Battlegrounds (PUBG), Horizon Zero Dawn.

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. 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 EPYC 7513 is more energy efficient than the EPYC 7643 since it has less power consumption: 200W vs. 225W. 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

Let's say you plan to use the processor not only for gaming, but also for machine learning, video editing or video rendering, streaming, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum efficiency, the processor 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 find out whether the program 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 run, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most helpful will be the release date of the processor and the possibility of overclocking it. The newer the processor, the longer it will last in your computer. 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, increasing its performance, then it will still be able to produce maximum FPS even in new games. The economy are obvious! Accordingly, 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 7513 is 11% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 16 more core than EPYC 7513. 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 7513 is better: 4
The number of parameters for which AMD EPYC 7643 is better: 24
However, it should be understood that all the data in the text above do not mean that you should be guided entirely by them and trust a simple quantitative comparison. Be sure to watch benchmarks video and read the reviews of of people who bought AMD EPYC 7513 and AMD EPYC 7643 before deciding which CPU to buy for gaming and which not.
