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 7402 | 64% |
The number of this parameter shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, EPYC 7662 is 11% better than EPYC 7402. The data source is several popular tests. More detailed information of the benchmarks is below.
Gaming performance
Summary result of all game benchmarks.| EPYC 7662 | 84% |
EPYC 7402 | 67% |
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 run 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 other games in which CPU comparisons were performed: Microsoft Flight Simulator, Shadow of the Tomb Raider, Monster Hunter World, Metro Exodus, The Witcher 3: Wild Hunt, Control, Hitman 3, Half-Life: Alyx, Counter-Strike: Global Offensive (CS GO), League of Legends (LOL), Forza Horizon 4, DOTA 2A, Resident Evil 7 Biohazard, Horizon Zero Dawn, PlayerUnknown's Battlegrounds (PUBG), Ghostrunner, NBA 2K20, Battlefield V.
Gaming benchmark| Fortnite | 149.3 | 118.6 | | Valorant | 169.6 | 134.7 | | Cyberpunk 2077 | 95.0 | 75.5 | | Apex Legends | 159.5 | 126.7 | | Call of Duty Warzone | 127.2 | 101.1 | | Overwatch | 137.4 | 109.1 | | Red Dead Redemption 2 | 117.1 | 93.0 | | DOOM Eternal | 84.8 | 67.4 | | Warzone | 132.3 | 105.1 | | Assassin's Creed | 142.5 | 113.2 | | Valheim | 140.8 | 111.8 |
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 comparisons not only were the equipped with different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 4K, 2K or FullHD. Therefore, the game benchmark data is approximate. But all video cards met the average system requirements of games. To be sure exactly how much performance 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 7402 | 20% |
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 7402 is more energy efficient than the EPYC 7662 since it has less power consumption: 225W vs. 180W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need 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 benchmarksIf you plan to use the processor not only for gaming, but also for machine learning, video rendering or video editing, streaming, programming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the processor uses all cores and threads that it has to the maximum to reach maximum performance. 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 program you are going to use on your computer supports multi-threaded mode. Since there are still many programs that use only one core to work, and all the advantages 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 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!
