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

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 that were in the comparisons not only did they have 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. 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.

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 Ryzen 9 3900XT is more energy efficient than the Ryzen 9 7900X3D since it has less power consumption: 170W vs. 105W. 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 machine learning, streaming, programming, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU uses all threads and cores that it has to the maximum to achieve 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 find out whether the program 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 useful will be the the possibility of overclocking it and release date of the processor. 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 new games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The economy are obvious!
