Summary benchmark results

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

Processor Benchmark
EPYC 764381% EPYC 776389%
The number of this parameter shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, EPYC 7763 is 8% better than EPYC 7643. The data source is several popular tests. More detailed information of the benchmarks is below.

Gaming performance
Summary result of all game benchmarks.
EPYC 764380% EPYC 776368%
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 the cost of this processor reaches several tens of thousands of dollars. Therefore, if you think that the selected CPU has a low game result, 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: DOTA 2A, Battlefield V, Half-Life: Alyx, Metro Exodus, PlayerUnknown's Battlegrounds (PUBG), League of Legends (LOL), Control, Monster Hunter World, Ghostrunner, Horizon Zero Dawn, The Witcher 3: Wild Hunt, Microsoft Flight Simulator, NBA 2K20, Hitman 3, Shadow of the Tomb Raider, Counter-Strike: Global Offensive (CS GO), Forza Horizon 4, Resident Evil 7 Biohazard.

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 764318% EPYC 776315%
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 7643 is more energy efficient than the EPYC 7763 since it has less power consumption: 225W vs. 280W. 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

For example you want to use the processor not only for gaming, but also for video rendering or video editing, machine learning, programming, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the CPU includes all cores and threads that it has. You will learn this data from the benchmark tables below. Before you take into account the data from these tests, be sure to find out whether the program 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 run, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most useful will be the release date of the processor and the possibility of overclocking it. The newer the processor, the longer it will last you. 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 the newest games. Accordingly, you do not 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 7763 is 6% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7763 has 16 more core than EPYC 7643. 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 7643 is better: 14
The number of parameters for which AMD EPYC 7763 is better: 14
   Although it should be realized that all the number in the article above do not mean that taking them into account you should completely trust a simple quantitative comparison. Be sure to watch the video tests and read the opinion of of people who bought AMD EPYC 7643 and AMD EPYC 7763 before making a decision which processor to buy for gaming and which not.
