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 the cost of this processor reaches several tens of thousands of dollars. And if it seems to you that the selected CPU has a low game result, just look at the FPS that it produces in real games in the final table below.
List of other games in which CPU comparisons were performed: Microsoft Flight Simulator, NBA 2K20, Half-Life: Alyx, The Witcher 3: Wild Hunt, Forza Horizon 4, Battlefield V, Horizon Zero Dawn, Ghostrunner, Monster Hunter World, PlayerUnknown's Battlegrounds (PUBG), Metro Exodus, Control, Shadow of the Tomb Raider, League of Legends (LOL), Counter-Strike: Global Offensive (CS GO), Hitman 3, Resident Evil 7 Biohazard, DOTA 2A.

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.

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 i9-11900K is more energy efficient than the Core i9-11900KF as it consumes less power: 125W 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 editing or video rendering, streaming, programming, machine learning, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum performance, the CPU uses all threads and cores 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. Since there are still many programs that can 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 most helpful will be the release date of the processor and the possibility of overclocking it. The newer the processor, the longer it will last in your computer. 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 in the newest games. The economy 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. 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 i9-11900KF is better: 0
The number of parameters for which Intel Core i9-11900K is better: 21
However, 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. Be sure to watch the video tests and read the reviews of of people who bought Intel Core i9-11900KF and Intel Core i9-11900K before deciding which of the CPUs to buy for gaming.
