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

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: 2K, 4K or FullHD. 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 compare it in one assembly with the video card that is installed in your computer.


Power consumption
Ryzen 9 7900X41% EPYC 764318%
To make a final resolution 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 Ryzen 9 7900X is more energy efficient than the EPYC 7643 since it has less power consumption: 170W vs. 225W. Power consumption is especially important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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 programming, streaming, video rendering or video editing, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum performance, the CPU turns on all cores and threads that it has. You will learn 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. Since there are still many programs that use only one core to work, and all the benefit of multi-core mode turns out to be unnecessary.

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 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. If the processor can be overclocked, thereby increasing its performance, then it will still be able to produce maximum FPS in the newest games. The savings 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 Ryzen 9 7900X is 51% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 36 more core than Ryzen 9 7900X. 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 Ryzen 9 7900X is better: 15
The number of parameters for which AMD EPYC 7643 is better: 20
   However, it should be understood that all the data in the table above do not mean that taking them into account you should undividedly trust a simple comparison of these figures. Be sure to watch the testing video and read the opinion of real owners of AMD Ryzen 9 7900X and AMD EPYC 7643 before making a selection which CPU to buy for gaming and which not.
