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 this processor costs 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 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 video cards and different amounts of RAM. 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. To be sure exactly how much performance 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 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 W-3175X since it has less power consumption: 225W vs. 255W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, it will be useful to 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 want to use the processor not only for gaming, but also for video editing or video rendering, streaming, machine learning, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum performance, the CPU includes all cores and threads that it has. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to find out whether the software that you are going to use on your computer can work in multi-threaded mode. Because there are still many programs that use only one core to run, and all the benefit of multi-core mode are unused.

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. When the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS in new games. The economy are obvious! Accordingly, 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 Xeon W-3175X is 25% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 20 more core than Xeon W-3175X. 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 W-3175X is better: 12
Although it should be understood that all the figures that you have looked at here do not mean that taking them into account you should entirely trust a simple comparison of these figures. Be sure to watch the testing video and read the opinion of of people who bought AMD EPYC 7643 and Intel Xeon W-3175X before making a selection which of the processors to buy for gaming.
