Processor comparisons   12-06-2021
   For example you can't decide which processor to buy, you can make a decision after reading the detailed tests Intel Core i9-11900KB vs Intel Core i9-11900K and decide which is better for games or simple use for rendering, streaming, video editing, machine learning, programming. Here is useful information from real streaming and video editing tests or several benchmarks. A step-by-step analysis of all the specifications, so that it can be easier to read, is summarized in the table.
   From the video comparison, you can get the results of parallel examination in special test applications such as PassMark, Handbrake, PCMark 10, Dolphin Emulator, World of Tanks enCore Benchmark, AIDA64, MATLAB, 3DMark, VeraCrypt, WPrime, RealBench, Blender, Geekbench 5.2, 7zip, Gears 5, UserBenchmark, DaVinci Resolve Studio, SuperPi, Blender, Prime95, Cinebench 23 (20, 15), Furmark.

Summary benchmark results

As a percentage of the maximum value based on a sample from the entire base of all processors

Processor Benchmark
Core i9-11900KB66% Core i9-11900K65%
The number of this parameter shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Core i9-11900KB is 1% better than Core i9-11900K. The data source is several popular tests. Detailed information can be found below.

Gaming performance
Summary result of all game benchmarks.
Core i9-11900KB61% Core i9-11900K61%
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 this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a little game result, 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: Monster Hunter World, Control, Ghostrunner, Hitman 3, Forza Horizon 4, Horizon Zero Dawn, Resident Evil 7 Biohazard, League of Legends (LOL), Microsoft Flight Simulator, NBA 2K20, Battlefield V, DOTA 2A, Counter-Strike: Global Offensive (CS GO), Metro Exodus, Half-Life: Alyx, PlayerUnknown's Battlegrounds (PUBG), The Witcher 3: Wild Hunt, 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 amounts of RAM and different video cards. 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. 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.


Power consumption
Core i9-11900KB104% Core i9-11900K52%
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 i9-11900KB is more energy efficient than the Core i9-11900K 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

For example you want to use the processor not only for gaming, but also for video editing or video rendering, streaming, programming, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU includes all threads and cores that it has to the maximum to reach maximum efficiency. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to check whether the program 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 turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most useful. The later the processor is released, the longer it will last in your computer. And the easier it will be to upgrade the system in the future. The same can be said about overclocking. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS even in the newest games. It turns out that there is no longer a need to buy a new CPU to enjoy the games any longer. The economy are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i9-11900K 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 i9-11900K is better: 3
   Although it should be realized that all the figures in the text above do not mean that taking them into account you should completely trust a simple quantitative comparison. Better to watch the testing video and read the reviews of of people who bought Intel Core i9-11900KB and Intel Core i9-11900K before making a selection which of the processors to buy for gaming.
