Summary benchmark results

As a percentage of the maximum value based on a sample from the entire base of all processors
Processor Benchmark
Core i9-12900KS85% EPYC 764375%
This value shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Core i9-12900KS is 11% better than EPYC 7643. The data source is several popular tests. Detailed information can be found below.

Gaming performance
Summary result of all game benchmarks.
Core i9-12900KS67% EPYC 764380%
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: Shadow of the Tomb Raider, NBA 2K20, League of Legends (LOL), Forza Horizon 4, Monster Hunter World, Resident Evil 7 Biohazard, Half-Life: Alyx, Control, Horizon Zero Dawn, PlayerUnknown's Battlegrounds (PUBG), Metro Exodus, Counter-Strike: Global Offensive (CS GO), Hitman 3, Microsoft Flight Simulator, DOTA 2A, Battlefield V, Ghostrunner, The Witcher 3: Wild Hunt.

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
Core i9-12900KS48% EPYC 764318%
To make a finishing choice 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 Core i9-12900KS is more energy efficient than the EPYC 7643 since it has less power consumption: 150W vs. 225W. Power consumption is particularly 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 machine learning, streaming, programming, video rendering or video editing, then the main parameter for you is its performance in multi-threaded mode. In this mode, to achieve maximum performance, the processor turns on all threads and cores 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 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 useful. The newer the processor, 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. When the processor can be overclocked, thereby increasing its performance, then it will still be able to produce maximum FPS even in new games. The economy are obvious! Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer.

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i9-12900KS is 42% better than EPYC 7643 in terms of CPU frequency. Another difference is that EPYC 7643 has 32 more core than Core i9-12900KS. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which Intel Core i9-12900KS is better: 22
The number of parameters for which AMD EPYC 7643 is better: 15
   However, it should be realized that the summary data in the table above do not mean that taking them into account you should completely trust a simple comparison of these numbers. Be sure to watch the video tests and read the opinion of of people who bought Intel Core i9-12900KS and AMD EPYC 7643 before making a decision which processor to buy for gaming and which not.
