Summary benchmark results

As a percentage of the maximum value based on a sample from the entire base of all processors
Processor Benchmark
EPYC 764375% Ryzen 9 390064%
This value shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, EPYC 7643 is 14% better than Ryzen 9 3900. The data source is several popular tests. Detailed information can be found below.

Gaming performance
Summary result of all game benchmarks.
EPYC 764380% Ryzen 9 390061%
The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. 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, just look at the FPS that it produces in real games in the final table below.
List of less popular games in which CPU comparisons were performed: Hitman 3, Counter-Strike: Global Offensive (CS GO), Monster Hunter World, The Witcher 3: Wild Hunt, Half-Life: Alyx, Resident Evil 7 Biohazard, Microsoft Flight Simulator, PlayerUnknown's Battlegrounds (PUBG), Metro Exodus, NBA 2K20, Forza Horizon 4, League of Legends (LOL), Battlefield V, Horizon Zero Dawn, Ghostrunner, Shadow of the Tomb Raider, DOTA 2A, Control.

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: 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 compare it in one assembly with the video card that is installed in your computer.


Power consumption
EPYC 764318% Ryzen 9 390067%
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 3900 is more energy efficient than the EPYC 7643 since it has less power consumption: 225W vs. 65W. 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 video rendering or video editing, programming, streaming, machine learning, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum efficiency, the processor turns on 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 check whether the program you are going to use on your computer supports multi-threaded mode. Since there are still many programs that 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 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 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 in new games. The economy are obvious! Accordingly, you do not need to buy a new CPU to enjoy the games any longer.
