The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. 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 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 tested computers not only did they have 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. 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 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 7543 is more energy efficient than the EPYC 7662 since it has less power consumption: 225W 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 video rendering or video editing, programming, machine learning, streaming, 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 achieve 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. Because there are still many programs that can 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 most helpful will be the release date of the processor and the possibility of overclocking it. The later the processor is released, the longer it will last you. And the easier it will be to upgrade the system later. 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 even in new 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 7543 is 28% better than EPYC 7662 in terms of CPU frequency. Another difference is that EPYC 7662 has 32 more core than EPYC 7543. 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 7662 is better: 23
The number of parameters for which AMD EPYC 7543 is better: 6
Although it should be understood that all the figures in the article above do not mean that taking them into account you should entirely trust a simple quantitative comparison. Better to watch the video tests and read the opinion of real owners of AMD EPYC 7662 and AMD EPYC 7543 before deciding which of the CPUs to buy for gaming.
