For the maximum in this test, the results of the most powerful processor in the site database are taken. 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 processors were compared: Horizon Zero Dawn, Monster Hunter World, Half-Life: Alyx, Shadow of the Tomb Raider, Ghostrunner, Battlefield V, PlayerUnknown's Battlegrounds (PUBG), Resident Evil 7 Biohazard, Microsoft Flight Simulator, DOTA 2A, Control, Hitman 3, The Witcher 3: Wild Hunt, Metro Exodus, Forza Horizon 4, NBA 2K20, Counter-Strike: Global Offensive (CS GO), League of Legends (LOL).

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: FullHD, 2K or 4K. So the game benchmark data is approximate. But all video cards met the average system requirements of games. You will get more accurate information about how powerful 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. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Ryzen 3 3100 is more energy efficient than the Core i5-8400 since it has less power consumption: 65W vs. 65W. Power consumption is especially important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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

For example you want to use the processor not only for gaming, but also for streaming, video editing or video rendering, machine learning, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU turns on 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. 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 most helpful will be the release date of the processor and the possibility of overclocking it. The newer the processor, the longer it will last in your computer. And the easier it will be to upgrade the system in the future. The same benefits from the presence of overclocking. If the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS even in new games. The economy 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 Ryzen 3 3100 is 22% better than Core i5-8400 in terms of CPU frequency. Another difference is that Core i5-8400 has 2 more core than Ryzen 3 3100. 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 3 3100 is better: 28
The number of parameters for which Intel Core i5-8400 is better: 8
Although it should be understood that all the number in the article above do not mean that taking them into account you should completely trust a simple quantitative comparison. Be sure to watch benchmarks video and read the opinion of of people who bought AMD Ryzen 3 3100 and Intel Core i5-8400 before making a decision which of the processors to buy for gaming.
