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

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 amounts of RAM and different video cards. But users also tested them at different screen resolutions: 4K, 2K or FullHD. 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 finishing decision 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 7713 is more energy efficient than the EPYC 7643 since it has less power consumption: 225W vs. 225W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, it will be useful 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

For example you want 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, to reach maximum performance, the CPU includes all threads and cores 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 you. 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 in new games. Accordingly, there is no longer a 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 EPYC 7643 is 13% better than EPYC 7713 in terms of CPU frequency. Another difference is that EPYC 7713 has 16 more core than EPYC 7643. 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 7713 is better: 25
The number of parameters for which AMD EPYC 7643 is better: 1
However, it should be realized that all the data in the table above do not mean that taking them into account you should totally trust a simple comparison of these figures. Be sure to watch the video tests and read the reviews of real owners of AMD EPYC 7713 and AMD EPYC 7643 before making a choice which processor to buy for gaming and which not.
