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 the cost of this processor reaches several tens of thousands of dollars. Therefore, if you think that the selected CPU has a little 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 tested computers not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, 4K or FullHD. Therefore, 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 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. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Ryzen 9 3900X is more energy efficient than the EPYC 7543 since it has less power consumption: 225W vs. 105W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you must 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

For example you want to use the processor not only for gaming, but also for machine learning, streaming, programming, video rendering or video editing, then the main parameter for you is its performance in multi-threaded mode. In this mode, to achieve maximum performance, the processor turns on all threads and cores that it has. You will find out this data from the benchmark tables below. Before you take into account 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 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 in your computer. And the easier it will be to upgrade the system later. 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 in the newest games. Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer. The savings are obvious!
