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 tested computers not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: FullHD, 2K 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 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 7452 is more energy efficient than the EPYC 7663 since it has less power consumption: 155W vs. 240W. 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

If you want to use the processor not only for gaming, but also for machine learning, video editing or video rendering, streaming, programming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the processor uses all threads and cores that it has. You will find out this data from the benchmark tables below. Before using the data from these tests, be sure to make sure that the software 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 are unused.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most helpful. 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 continue to maintain maximum FPS in new games. The economy are obvious! It turns out that there is no longer a 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 7452 is 14% better than EPYC 7663 in terms of CPU frequency. Another difference is that EPYC 7663 has 24 more core than EPYC 7452. 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 7452 is better: 5
The number of parameters for which AMD EPYC 7663 is better: 27
All the data that you have looked at here do not mean that taking them into account you should completely trust a simple comparison of these figures. Better to watch benchmarks video and read the opinion of real owners of AMD EPYC 7452 and AMD EPYC 7663 before deciding which processor to buy for gaming and which not.
