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

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 video cards and different amounts of RAM. But users also tested them at different screen resolutions: 4K, 2K or FullHD. Therefore, 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.

Software benchmarks

Let's say you want to use the processor not only for gaming, but also for machine learning, streaming, programming, video rendering or video editing, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the CPU includes all cores and threads that it has. You will find out this data from the benchmark tables below. Before using the data from these tests, be sure to check whether the software you are going to use on your computer supports multi-threaded mode. Since there are still many programs that can use only one core to work, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most useful 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 in the future. The same benefits from the presence of overclocking. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS in new games. Accordingly, there is no longer a 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 Core i5-8600 is 9% better than Core i5-8400 in terms of CPU frequency. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which Intel Core i5-8600 is better: 22
The number of parameters for which Intel Core i5-8400 is better: 4
However, 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 comparison of these figures. Better to watch the testing video and read the opinion of of people who bought Intel Core i5-8600 and Intel Core i5-8400 before making a decision which processor to buy for gaming and which not.
