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

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.

To make a final resolution 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 3900 is more energy efficient than the Ryzen 7 5800X since it has less power consumption: 65W vs. 105W. Power consumption is especially 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 benchmarks

If you plan to use the processor not only for gaming, but also for machine learning, video editing or video rendering, streaming, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum efficiency, the processor turns on 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 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 benefit of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most helpful will be the release date of the processor and the possibility of overclocking it. The later the processor is released, 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 still be able to produce maximum FPS even in the newest games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The economy are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Ryzen 7 5800X is 18% better than Ryzen 9 3900 in terms of CPU frequency. Another difference is that Ryzen 9 3900 has 4 more core than Ryzen 7 5800X. 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 Ryzen 9 3900 is better: 23
The number of parameters for which AMD Ryzen 7 5800X is better: 10
However, it should be understood that all the figures in the text above do not mean that taking them into account you should undividedly trust a simple quantitative comparison. Better to watch the video tests and read the reviews of real owners of AMD Ryzen 9 3900 and AMD Ryzen 7 5800X before making a selection which of the CPUs to buy for gaming.
