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 play games. Because this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a little game result, look at the FPS that it produces in real games in the summary table below.
List of other games in which processors were compared: Battlefield V, Counter-Strike: Global Offensive (CS GO), DOTA 2A, Hitman 3, Forza Horizon 4, NBA 2K20, The Witcher 3: Wild Hunt, Resident Evil 7 Biohazard, Metro Exodus, Control, Horizon Zero Dawn, League of Legends (LOL), Ghostrunner, Shadow of the Tomb Raider, Microsoft Flight Simulator, Monster Hunter World, Half-Life: Alyx, 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 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, FullHD or 4K. 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.

To make a final resolution 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 Core i5-12400 is more energy efficient than the Ryzen 9 5900 since it has less power consumption: 65W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to 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

Let's say you want to use the processor not only for gaming, but also for machine learning, programming, streaming, 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 performance, the processor uses all cores and threads 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 program you are going to use on your computer supports multi-threaded mode. Because there are still many programs that use only one core to run, and all the advantages of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most helpful. 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. If the processor can be overclocked, thereby increasing its performance, then it will still be able to produce maximum FPS 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 Core i5-12400 is 9% better than Ryzen 9 5900 in terms of CPU frequency. Another difference is that Ryzen 9 5900 has 6 more core than Core i5-12400. 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 5900 is better: 23
The number of parameters for which Intel Core i5-12400 is better: 12
Although it should be understood that all the number that you have looked at here do not mean that taking them into account you should entirely trust a simple quantitative comparison. Better to watch benchmarks video and read the opinion of of people who bought AMD Ryzen 9 5900 and Intel Core i5-12400 before deciding which processor to buy for gaming and which not.
