For the maximum in this test, the results of the most powerful processor in the site database are taken. 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. Therefore, if you think that the selected CPU has a small game result, just look at the FPS that it produces in real games in the final table below.
List of other games in which processors were compared: Shadow of the Tomb Raider, DOTA 2A, Monster Hunter World, League of Legends (LOL), Microsoft Flight Simulator, Hitman 3, Counter-Strike: Global Offensive (CS GO), Horizon Zero Dawn, Ghostrunner, Metro Exodus, The Witcher 3: Wild Hunt, Battlefield V, NBA 2K20, Forza Horizon 4, Resident Evil 7 Biohazard, Half-Life: Alyx, Control, PlayerUnknown's Battlegrounds (PUBG).

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 amounts of RAM and different video cards. 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. 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.

To make a finishing choice 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 EPYC 7502 is more energy efficient than the EPYC 7642 since it has less power consumption: 225W vs. 180W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, you must 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

Let's say you want to use the processor not only for gaming, but also for video rendering or video editing, machine learning, streaming, programming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum performance, the CPU includes all threads and cores that it has. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to find out whether the software 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 in your computer. And the easier it will be to upgrade the system in the future. The same can be said about overclocking. If the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS even in new games. The economy are obvious! Accordingly, there is no longer a 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 7502 is 8% better than EPYC 7642 in terms of CPU frequency. Another difference is that EPYC 7642 has 16 more core than EPYC 7502. 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 7642 is better: 13
The number of parameters for which AMD EPYC 7502 is better: 17
Although it should be understood that all the number that you have looked at here do not mean that taking them into account you should fully trust a simple quantitative comparison. Be sure to watch the testing video and read the opinion of of people who bought AMD EPYC 7642 and AMD EPYC 7502 before making a choice which of the CPUs to buy for gaming.
