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 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, look at the FPS that it produces in real games in the final table below.
List of other games in which CPU comparisons were performed: Microsoft Flight Simulator, Shadow of the Tomb Raider, Monster Hunter World, Metro Exodus, The Witcher 3: Wild Hunt, Control, Hitman 3, Half-Life: Alyx, Counter-Strike: Global Offensive (CS GO), League of Legends (LOL), Forza Horizon 4, DOTA 2A, Resident Evil 7 Biohazard, Horizon Zero Dawn, PlayerUnknown's Battlegrounds (PUBG), Ghostrunner, NBA 2K20, Battlefield V.

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 video cards and different amounts of RAM. But users also tested them at different screen resolutions: FullHD, 2K 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 get acquainted with the benchmarks that are made with the same video card that is installed in your computer.

To make a final decision 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 Xeon Gold 6246R since it has less power consumption: 225W vs. 205W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to 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

For example you want to use the processor not only for gaming, but also for programming, video editing or video rendering, machine learning, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the processor 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 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 advantages of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most useful. 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 in new games. It turns out that there is no longer a 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 Xeon Gold 6246R is 32% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 32 more core than Xeon Gold 6246R. 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 7643 is better: 25
The number of parameters for which Intel Xeon Gold 6246R is better: 11
However, it should be realized that all the figures in the article above do not mean that taking them into account you should totally trust a simple comparison of these numbers. Be sure to watch benchmarks video and read the reviews of real owners of AMD EPYC 7643 and Intel Xeon Gold 6246R before making a choice which CPU to buy for gaming and which not.
