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 this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a little 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: Metro Exodus, Horizon Zero Dawn, Microsoft Flight Simulator, Counter-Strike: Global Offensive (CS GO), Control, PlayerUnknown's Battlegrounds (PUBG), Half-Life: Alyx, Resident Evil 7 Biohazard, Ghostrunner, Battlefield V, NBA 2K20, Monster Hunter World, Hitman 3, DOTA 2A, Shadow of the Tomb Raider, The Witcher 3: Wild Hunt, League of Legends (LOL), Forza Horizon 4.

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 video cards and different amounts of RAM. 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 finishing choice on which processor is better, you should also consider the generation of its core. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Ryzen 7 5700X is more energy efficient than the Ryzen 9 3900 as it consumes less power: 65W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you must know its TDP. 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 want to use the processor not only for gaming, but also for machine learning, streaming, video editing or video rendering, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to achieve maximum performance, the processor uses all threads and cores that it has. You will learn this data from the benchmark tables below. Before you take into account the data from these tests, be sure to check whether the software you are going to use on your computer supports multi-threaded mode. Because 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 processor release date and overclocking capability will be the most helpful. The later the processor is released, 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. If the processor can be overclocked, increasing its performance, then it will continue to maintain 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 Ryzen 7 5700X is 8% better than Ryzen 9 3900 in terms of CPU frequency. Another difference is that Ryzen 9 3900 has 4 more core than Ryzen 7 5700X. 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 7 5700X is better: 10
The number of parameters for which AMD Ryzen 9 3900 is better: 22
Although it should be understood that the summary data in the table above do not mean that taking them into account you should entirely trust a simple comparison of these figures. Better to watch the testing video and read the opinion of real owners of AMD Ryzen 7 5700X and AMD Ryzen 9 3900 before making a selection which of the CPUs to buy for gaming.
