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. Therefore, if you think that the selected CPU has a little game result, just look at the FPS that it produces in real games in the summary table below.

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: 4K, 2K or FullHD. 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 get acquainted with the benchmarks that are made with the same video card that is installed in your computer.

To make a finishing 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 3 3300X 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. Also, when choosing a processor cooling system, it will be useful 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 streaming, machine learning, video editing or video rendering, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the processor turns on all cores and threads that it has to the maximum to achieve maximum efficiency. 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 software that you are going to use on your computer can work in multi-threaded mode. Because there are still many programs that can use only one core to work, 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 useful. 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. When the processor can be overclocked, thereby increasing its performance, then it will continue to maintain 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 Ryzen 3 3300X is 26% better than Core i5-8400 in terms of CPU frequency. Another difference is that Core i5-8400 has 2 more core than Ryzen 3 3300X. 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 3300X is better: 30
The number of parameters for which Intel Core i5-8400 is better: 6
Although it should be understood that the summary data in the article above do not mean that taking them into account you should undividedly trust a simple comparison of these numbers. Better to watch the testing video and read the opinion of real owners of AMD Ryzen 3 3300X and Intel Core i5-8400 before deciding which processor to buy for gaming and which not.
