Summary benchmark results

As a percentage of the maximum value based on a sample from the entire base of all processors

Processor Benchmark
EPYC 774287% Ryzen 9 3900X68%
This shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, EPYC 7742 is 21% better than Ryzen 9 3900X. The data source is several popular tests. More detailed information of the benchmarks is below.

Gaming performance
Summary result of all game benchmarks.
EPYC 774292% Ryzen 9 3900X61%
The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. And it is clear that this is a server processor, on which no one will play games. Because this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a small game result, look at the FPS that it produces in real games in the final table below.
List of less popular games in which processors were compared: DOTA 2A, Hitman 3, Monster Hunter World, Forza Horizon 4, Horizon Zero Dawn, The Witcher 3: Wild Hunt, Shadow of the Tomb Raider, Resident Evil 7 Biohazard, Microsoft Flight Simulator, NBA 2K20, Ghostrunner, Half-Life: Alyx, Control, League of Legends (LOL), Metro Exodus, PlayerUnknown's Battlegrounds (PUBG), Battlefield V, Counter-Strike: Global Offensive (CS GO).

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. 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.


Power consumption
EPYC 774216% Ryzen 9 3900X42%
To make a finishing resolution 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 Ryzen 9 3900X is more energy efficient than the EPYC 7742 since it has less power consumption: 225W vs. 105W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, it will be useful 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

If 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, the CPU turns on all cores and threads 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 check whether the software you are going to use on your computer supports 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 processor release date and overclocking capability will be the most helpful. The newer the processor, the longer it will last you. And the easier it will be to upgrade the system later. 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 even in new games. It turns out that there is no longer a 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 Ryzen 9 3900X is 40% better than EPYC 7742 in terms of CPU frequency. Another difference is that EPYC 7742 has 52 more core than Ryzen 9 3900X. 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 7742 is better: 20
The number of parameters for which AMD Ryzen 9 3900X is better: 15
   However, it should be understood that all the figures that you have looked at here do not mean that you should be guided entirely by them and trust a simple quantitative comparison. Be sure to watch the video tests and read the opinion of of people who bought AMD EPYC 7742 and AMD Ryzen 9 3900X before making a decision which CPU to buy for gaming and which not.
