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 this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a low game result, just look at the FPS that it produces in real games in the summary table below.
List of other games in which CPU comparisons were performed: The Witcher 3: Wild Hunt, Metro Exodus, Microsoft Flight Simulator, Half-Life: Alyx, Battlefield V, Forza Horizon 4, Shadow of the Tomb Raider, PlayerUnknown's Battlegrounds (PUBG), Horizon Zero Dawn, Monster Hunter World, Control, Resident Evil 7 Biohazard, Hitman 3, Counter-Strike: Global Offensive (CS GO), DOTA 2A, Ghostrunner, NBA 2K20, 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 computers participating in the comparing not only were the equipped with different video cards and different amounts of RAM. But users also tested them at different screen resolutions: 2K, FullHD or 4K. So the game benchmark data is approximate. But all video cards met the average system requirements of games. To be sure exactly how much performance 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. 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 Core i5-7600K is more energy efficient than the Core i9-11900KF since it has less power consumption: 91W vs. 125W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need to know its TDP. It is necessary to count 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 plan to use the processor not only for gaming, but also for video rendering or video editing, machine learning, programming, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU uses all cores and threads that it has to the maximum to reach maximum performance. You will learn this data from the benchmark tables below. Before using 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. Since there are still many programs that use only one core to run, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most helpful will be the the possibility of overclocking it and release date of the processor. The newer the processor, 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, thereby increasing its performance, then it will still be able to produce maximum FPS even in the newest games. The savings are obvious! It turns out that 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 i5-7600K is 7% better than Core i9-11900KF in terms of CPU frequency. Another difference is that Core i9-11900KF has 4 more core than Core i5-7600K. 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 i5-7600K is better: 3
The number of parameters for which Intel Core i9-11900KF is better: 32
Although it should be realized that the summary data that you have looked at here do not mean that taking them into account you should entirely trust a simple comparison of these figures. Better to watch the testing video and read the reviews of of people who bought Intel Core i5-7600K and Intel Core i9-11900KF before making a decision which processor to buy for gaming and which not.
