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: Half-Life: Alyx, Battlefield V, The Witcher 3: Wild Hunt, Metro Exodus, Monster Hunter World, NBA 2K20, Forza Horizon 4, Hitman 3, DOTA 2A, Ghostrunner, League of Legends (LOL), Shadow of the Tomb Raider, PlayerUnknown's Battlegrounds (PUBG), Horizon Zero Dawn, Microsoft Flight Simulator, Resident Evil 7 Biohazard, Counter-Strike: Global Offensive (CS GO), 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 computers that were in the comparisons not only did they have 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. 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.


Power consumption
Core i5-6600K51% Core i5-940056%
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 i5-9400 is more energy efficient than the Core i5-6600K as it consumes less power: 91W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to know its TDP. 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 video editing or video rendering, machine learning, streaming, programming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum performance, the processor turns on all threads and cores that it has. You will learn 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. Because there are still many programs that use only one core to run, 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 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. When the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS even in the newest games. The savings 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 Core i5-6600K is 17% better than Core i5-9400 in terms of CPU frequency. Another difference is that Core i5-9400 has 2 more core than Core i5-6600K. 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 i5-6600K is better: 2
The number of parameters for which Intel Core i5-9400 is better: 31
   Although it should be understood that all the number in the table above do not mean that taking them into account you should undividedly trust a simple comparison of these figures. Better to watch the testing video and read the reviews of real owners of Intel Core i5-6600K and Intel Core i5-9400 before making a selection which of the processors to buy for gaming.
