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 run games. Because this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a small game result, just 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 video cards and different amounts of RAM. But users also tested them at different screen resolutions: 4K, 2K 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 get acquainted with the benchmarks that are made with the same video card that is installed in your computer.

To make a finishing 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 7443 is more energy efficient than the EPYC 7543 since it has less power consumption: 200W vs. 225W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, you must 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

Let's say you want to use the processor not only for gaming, but also for machine learning, programming, streaming, video editing or video rendering, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU uses 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 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 can use only one core to run, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most useful will be the the possibility of overclocking it and release date of the processor. The later the processor is released, the longer it will last in your computer. And the easier it will be to upgrade the system in the future. The same can be said about overclocking. If the processor can be overclocked, thereby increasing its performance, then it will still be able to produce maximum FPS in new games. Accordingly, you do not 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 7443 is 1% better than EPYC 7543 in terms of CPU frequency. Another difference is that EPYC 7543 has 8 more core than EPYC 7443. 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 7443 is better: 3
The number of parameters for which AMD EPYC 7543 is better: 25
All the data in the article above do not mean that taking them into account you should entirely trust a simple quantitative comparison. Be sure to watch benchmarks video and read the reviews of of people who bought AMD EPYC 7443 and AMD EPYC 7543 before deciding which CPU to buy for gaming and which not.
