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 the cost of this processor reaches 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: Battlefield V, Microsoft Flight Simulator, League of Legends (LOL), Forza Horizon 4, Horizon Zero Dawn, NBA 2K20, Hitman 3, Control, Ghostrunner, Half-Life: Alyx, Shadow of the Tomb Raider, Metro Exodus, Resident Evil 7 Biohazard, Monster Hunter World, The Witcher 3: Wild Hunt, DOTA 2A, PlayerUnknown's Battlegrounds (PUBG), 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 that were in the comparisons not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, FullHD 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 compare it in one assembly with the video card that is installed in your computer.


Power consumption
EPYC 766312% EPYC 764318%
To make a final 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 7643 is more energy efficient than the EPYC 7663 as it consumes less power: 240W vs. 225W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, you must 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

If you plan to use the processor not only for gaming, but also for programming, machine learning, video editing or video rendering, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to achieve maximum performance, the CPU includes all threads and cores that it has. You will find out this data from the benchmark tables below. Before using 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 turns out to be unnecessary.

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 later the processor is released, 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. When the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS in new games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The savings 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 7663 in terms of CPU frequency. Another difference is that EPYC 7663 has 8 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 7663 is better: 23
The number of parameters for which AMD EPYC 7643 is better: 4
   However, it should be understood that all the data in the text above do not mean that taking them into account you should completely trust a simple quantitative comparison. Be sure to watch the testing video and read the reviews of real owners of AMD EPYC 7663 and AMD EPYC 7643 before making a choice which of the processors to buy for gaming.
