The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. 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. And if it seems to you that the selected CPU has a low game result, look at the FPS that it produces in real games in the final 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 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 compare it in one assembly with the video card that is installed in your computer.

To make a finishing 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 EPYC 7373X is more energy efficient than the EPYC 7643 as it consumes less power: 240W vs. 225W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, it will be useful 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 plan to use the processor not only for gaming, but also for video rendering or video editing, machine learning, programming, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU includes all threads and cores that it has to the maximum to reach maximum efficiency. You will learn this data from the benchmark tables below. Before you take into account the data from these tests, be sure to make sure that the program that you are going to use on your computer can work in multi-threaded mode. Because 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 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 in the future. The same benefits from the presence of overclocking. When the processor can be overclocked, thereby increasing its performance, then it will still be able to produce maximum FPS even in the newest games. The savings are obvious! It turns out that 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 EPYC 7373X is 24% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 32 more core than EPYC 7373X. 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 7373X is better: 5
The number of parameters for which AMD EPYC 7643 is better: 24
Although it should be understood that the summary data that you have looked at here do not mean that you should be guided entirely by them and trust a simple quantitative comparison. Better to watch benchmarks video and read the reviews of of people who bought AMD EPYC 7373X and AMD EPYC 7643 before making a choice which CPU to buy for gaming and which not.
