Summary benchmark results

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

Processor Benchmark
EPYC 734372% EPYC 764381%
This value shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, EPYC 7643 is 11% better than EPYC 7343. The data source is several popular tests. Detailed information can be found below.

Gaming performance
Summary result of all game benchmarks.
EPYC 734368% EPYC 764380%
The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. And of course, 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, look at the FPS that it produces in real games in the summary table below.
List of other games in which CPU comparisons were performed: Control, DOTA 2A, The Witcher 3: Wild Hunt, Metro Exodus, Microsoft Flight Simulator, NBA 2K20, Hitman 3, PlayerUnknown's Battlegrounds (PUBG), Half-Life: Alyx, Shadow of the Tomb Raider, Monster Hunter World, Forza Horizon 4, Resident Evil 7 Biohazard, Ghostrunner, Counter-Strike: Global Offensive (CS GO), League of Legends (LOL), Horizon Zero Dawn, Battlefield V.

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 computers participating in the comparing not only were the equipped with different video cards and different amounts of RAM. 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 734320% EPYC 764318%
To make a final 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 EPYC 7343 is more energy efficient than the EPYC 7643 as it consumes less power: 190W vs. 225W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, it will be useful to 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

If you plan to use the processor not only for gaming, but also for programming, machine learning, streaming, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum efficiency, the CPU turns on all cores and threads 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 check whether the software you are going to use on your computer supports multi-threaded mode. Since there are still many programs that use only one core to run, and all the benefit of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most useful. 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, increasing its performance, then it will continue to maintain maximum FPS in new games. Accordingly, 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 EPYC 7343 is 28% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 32 more core than EPYC 7343. 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 7343 is better: 3
The number of parameters for which AMD EPYC 7643 is better: 25
   However, it should be realized that all the number in the article above do not mean that you should be guided entirely by them and trust a simple comparison of these figures. Better to watch the testing video and read the opinion of of people who bought AMD EPYC 7343 and AMD EPYC 7643 before making a decision which CPU to buy for gaming and which not.
