The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. And it is clear that this is a server processor, on which no one will run 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, just look at the FPS that it produces in real games in the final table below.
List of other games in which processors were compared: DOTA 2A, Battlefield V, NBA 2K20, Monster Hunter World, Metro Exodus, Half-Life: Alyx, Hitman 3, Counter-Strike: Global Offensive (CS GO), The Witcher 3: Wild Hunt, Horizon Zero Dawn, League of Legends (LOL), PlayerUnknown's Battlegrounds (PUBG), Control, Forza Horizon 4, Microsoft Flight Simulator, Shadow of the Tomb Raider, Ghostrunner, 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: 2K, FullHD or 4K. So 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 compare it in one assembly with the video card that is installed in your computer.

Power consumption

16%

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 7742 since it has less power consumption: 180W vs. 225W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, it will be useful to 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

If you plan to use the processor not only for gaming, but also for programming, video rendering or video editing, machine learning, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the processor uses 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 make sure that the program 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 helpful. 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, increasing its performance, then it will continue to maintain maximum FPS even in the newest games. The savings are obvious! Accordingly, you do not 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 EPYC 7402 is 19% better than EPYC 7742 in terms of CPU frequency. Another difference is that EPYC 7742 has 40 more core than EPYC 7402. 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 7402 is better: 7
The number of parameters for which AMD EPYC 7742 is better: 24
However, it should be understood that all the number in the article above do not mean that taking them into account you should fully trust a simple comparison of these numbers. Better to watch the video tests and read the opinion of of people who bought AMD EPYC 7402 and AMD EPYC 7742 before making a choice which processor to buy for gaming and which not.
