AMD EPYC 7543 vs AMD EPYC 7643

Processor comparisons   25-03-2021
   Perhaps you can't decide which processor to buy, you can make a decision by looking at the AMD EPYC 7543 vs AMD EPYC 7643 tests and see which is better for games or simple use for programming, machine learning, video editing, rendering, streaming. Here is useful information from real video editing and streaming tests or many benchmarks. A careful analysis of all the technical characteristics, to make it easier to understand, is presented in the form of the table.
   From the video comparison, you can get the results of parallel examination in synthetic type tests like Gears 5, RealBench, UserBenchmark, Dolphin Emulator, World of Tanks enCore Benchmark, PCMark 10, 7zip, DaVinci Resolve Studio, Cinebench 23 (20, 15), 3DMark, SuperPi, Blender, Handbrake, AIDA64, PassMark, WPrime, Blender, Geekbench 5.2, Prime95, VeraCrypt, Furmark, MATLAB.

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

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 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. 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 754320% EPYC 764318%
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 EPYC 7543 is more energy efficient than the EPYC 7643 since it has less power consumption: 225W 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 calculate so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

Let's say you want to use the processor not only for gaming, but also for video rendering or video editing, streaming, programming, machine learning, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum performance, the processor 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 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 can use only one core to run, and all the advantages of multi-core mode turns out to be unnecessary.

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 you. 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 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 EPYC 7543 is 17% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 16 more core than EPYC 7543. 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 7543 is better: 3
The number of parameters for which AMD EPYC 7643 is better: 23
   However, it should be understood that all the figures in the table above do not mean that taking them into account you should totally trust a simple quantitative comparison. Be sure to watch benchmarks video and read the opinion of real owners of AMD EPYC 7543 and AMD EPYC 7643 before deciding which processor to buy for gaming and which not.
