The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. 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, look at the FPS that it produces in real games in the final 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: FullHD, 2K 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 get acquainted with the benchmarks that are made with the same video card that is installed in your computer.

To make a finishing choice 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 i9-11900F is more energy efficient than the Core i9-11900KF since it has less power consumption: 65W vs. 125W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, you must 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 want to use the processor not only for gaming, but also for video rendering or video editing, streaming, programming, machine learning, 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 turns on all cores and threads that it has. 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 run, and all the advantages of multi-core mode turns out to be unnecessary.

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 in the future. The same benefits from the presence of overclocking. If the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS even in new games. The economy 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 i9-11900KF is 28% better than Core i9-11900F in terms of CPU frequency. 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 i9-11900F is better: 14
The number of parameters for which Intel Core i9-11900KF is better: 12
All the data in the table above do not mean that taking them into account you should completely trust a simple comparison of these figures. Better to watch the video tests and read the opinion of of people who bought Intel Core i9-11900F and Intel Core i9-11900KF before making a selection which of the CPUs to buy for gaming.
