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 run 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, 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: Half-Life: Alyx, The Witcher 3: Wild Hunt, DOTA 2A, Monster Hunter World, Resident Evil 7 Biohazard, Horizon Zero Dawn, NBA 2K20, Control, Microsoft Flight Simulator, Ghostrunner, Metro Exodus, Counter-Strike: Global Offensive (CS GO), Forza Horizon 4, League of Legends (LOL), PlayerUnknown's Battlegrounds (PUBG), Hitman 3, Battlefield V, Shadow of the Tomb Raider.

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 comparisons 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. 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 compare it in one assembly with the video card that is installed in your computer.


Power consumption
Core i9-11900KB104% Core i9-11900KF45%
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 i9-11900KB is more energy efficient than the Core i9-11900KF since it has less power consumption: 65W vs. 125W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, it will be useful 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

If you want to use the processor not only for gaming, but also for streaming, programming, machine learning, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum performance, the CPU uses all cores and threads that it has. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to make sure that the program that you are going to use on your computer can work in multi-threaded mode. Since there are still many programs that can use only one core to work, and all the advantages 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 useful. 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. When the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS 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 5% better than Core i9-11900KB 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 i9-11900KB is better: 24
The number of parameters for which Intel Core i9-11900KF is better: 3
   Although it should be understood that all the data in the table above do not mean that taking them into account you should completely trust a simple comparison of these numbers. Better to watch the testing video and read the opinion of of people who bought Intel Core i9-11900KB and Intel Core i9-11900KF before making a decision which CPU to buy for gaming and which not.
