Processor comparisons   12-06-2021
   Let's say you can't decide which processor to buy, you can make a choice by looking at the Intel Core i9-11900KB vs AMD Ryzen 7 5800X tests and see which is better for games or normal use for video editing, machine learning, rendering, streaming, programming. Here is useful information from real streaming and video editing tests or various benchmarks. A step-by-step analysis of all the specifications, so that it can be easier to understand, is summarized in the table.
   From the comparison video, you can get the results of joint testing in software tests like VeraCrypt, Gears 5, AIDA64, Prime95, MATLAB, Blender, Dolphin Emulator, Handbrake, SuperPi, Blender, UserBenchmark, Cinebench 23 (20, 15), PassMark, Furmark, 7zip, DaVinci Resolve Studio, RealBench, 3DMark, World of Tanks enCore Benchmark, GeekBench 6, 5.2, PCMark 10, WPrime.
   And how good the processors are in games:

The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. 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. 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 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 final resolution 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 Ryzen 7 5800X since it has less power consumption: 65W vs. 105W. Power consumption is especially important for laptops. And TDP should be taken into account when choosing a processor cooling system. It is necessary to calculate so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

If 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, to reach maximum efficiency, the processor includes all threads and cores that it has. 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. Because there are still many programs that can use only one core to work, and all the advantages 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 helpful. The later the processor is released, 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. If the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS in new games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The economy are obvious!
