Summary benchmark resultsAs a percentage of the maximum value based on a sample from the entire base of all processors
Processor Benchmark
| EPYC 7662 | 72% |
EPYC 7642 | 68% |
The number of this parameter shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, EPYC 7662 is 5% better than EPYC 7642. The data source is several popular tests. Detailed information can be found below.
Gaming performance
Summary result of all game benchmarks.| EPYC 7662 | 84% |
EPYC 7642 | 73% |
For the maximum in this test, the results of the most powerful processor in the site database are taken. 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. And if it seems to you that the selected CPU has a small game result, just look at the FPS that it produces in real games in the summary table below.
List of less popular games in which processors were compared: The Witcher 3: Wild Hunt, Monster Hunter World, NBA 2K20, Battlefield V, Horizon Zero Dawn, Ghostrunner, Microsoft Flight Simulator, Metro Exodus, League of Legends (LOL), Resident Evil 7 Biohazard, Counter-Strike: Global Offensive (CS GO), PlayerUnknown's Battlegrounds (PUBG), Forza Horizon 4, Shadow of the Tomb Raider, Control, DOTA 2A, Hitman 3, Half-Life: Alyx.
Gaming benchmark| Fortnite | 149.3 | 129.7 | | Valorant | 169.6 | 147.3 | | Cyberpunk 2077 | 95.0 | 82.5 | | Apex Legends | 159.5 | 138.5 | | Call of Duty Warzone | 127.2 | 110.5 | | Overwatch | 137.4 | 119.3 | | Red Dead Redemption 2 | 117.1 | 101.7 | | DOOM Eternal | 84.8 | 73.7 | | Warzone | 132.3 | 114.9 | | Assassin's Creed | 142.5 | 123.8 | | Valheim | 140.8 | 122.3 |
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 video cards and different amounts of RAM. But users also tested them at different screen resolutions: 2K, FullHD or 4K. So 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 7662 | 16% |
EPYC 7642 | 13% |
To make a final 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 7662 is more energy efficient than the EPYC 7642 as it consumes less power: 225W vs. 225W. Power consumption is particularly important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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 benchmarksFor example you want to use the processor not only for gaming, but also for video rendering or video editing, machine learning, programming, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum efficiency, the processor uses all cores and threads that it has. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to make sure that the software that you are going to use on your computer can work in multi-threaded mode. Since there are still many programs that use only one core to work, and all the benefit of multi-core mode are unused.

Comparison of specifications
In the specification comparison table, the most helpful will be the the possibility of overclocking it and release date of the processor. The newer the processor, the longer it will last in your computer. 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 in the newest 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 7642 is 13% better than EPYC 7662 in terms of CPU frequency. Another difference is that EPYC 7662 has 16 more core than EPYC 7642. 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 7662 is better: 23
The number of parameters for which AMD EPYC 7642 is better: 1
Although it should be realized that all the figures that you have looked at here do not mean that taking them into account you should entirely trust a simple quantitative comparison. Better to watch benchmarks video and read the reviews of real owners of AMD EPYC 7662 and AMD EPYC 7642 before making a choice which of the processors to buy for gaming.
