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 run games. Because the cost of this processor reaches several tens of thousands of dollars. And if it seems to you 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 less popular games in which processors were compared: DOTA 2A, Hitman 3, Monster Hunter World, Forza Horizon 4, Horizon Zero Dawn, The Witcher 3: Wild Hunt, Shadow of the Tomb Raider, Resident Evil 7 Biohazard, Microsoft Flight Simulator, NBA 2K20, Ghostrunner, Half-Life: Alyx, Control, League of Legends (LOL), Metro Exodus, PlayerUnknown's Battlegrounds (PUBG), Battlefield V, 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 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.


Power consumption
Core i9-12900K97% EPYC 764318%
To make a final resolution 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 Core i9-12900K is more energy efficient than the EPYC 7643 as it consumes less power: 125W vs. 225W. 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

Let's say you want to use the processor not only for gaming, but also for streaming, machine learning, video editing or video rendering, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU includes all cores and threads that it has to the maximum to achieve maximum efficiency. You will learn 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 processor release date and overclocking capability will be the most helpful. The later the processor is released, the longer it will last you. 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 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 economy are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i9-12900K is 41% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 32 more core than Core i9-12900K. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which Intel Core i9-12900K is better: 18
The number of parameters for which AMD EPYC 7643 is better: 19
   However, it should be understood that all the figures in the table above do not mean that you should be guided entirely by them and trust a simple comparison of these figures. Better to watch the video tests and read the reviews of real owners of Intel Core i9-12900K and AMD EPYC 7643 before making a selection which of the CPUs to buy for gaming.
