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. And if it seems to you that the selected CPU has a small game result, just look at the FPS that it produces in real games in the summary table below.

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.

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 EPYC 7643 is more energy efficient than the EPYC 9454P since it has less power consumption: 290W 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 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 plan to use the processor not only for gaming, but also for machine learning, programming, streaming, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum performance, the processor 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 check whether the software you are going to use on your computer supports multi-threaded mode. Since there are still many programs that can use only one core to run, 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 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, increasing its performance, then it will continue to maintain maximum FPS in new games. Accordingly, 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 EPYC 9454P is 16% better than EPYC 7643 in terms of CPU frequency. 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 9454P is better: 30
The number of parameters for which AMD EPYC 7643 is better: 2
However, it should be understood that all the data in the article above do not mean that you should be guided entirely by them and trust a simple quantitative comparison. Better to watch the video tests and read the opinion of of people who bought AMD EPYC 9454P and AMD EPYC 7643 before making a selection which processor to buy for gaming and which not.
