For the maximum in this test, the results of the most powerful processor in the site database are taken. And it is clear that this is a server processor, on which no one will play games. Because this processor costs 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 summary 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: 4K, 2K or FullHD. So 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 decision 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 i7-11700B is more energy efficient than the Core i7-11700KF as it consumes less power: 65W vs. 125W. 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 plan to use the processor not only for gaming, but also for machine learning, programming, streaming, video editing or video rendering, then the main parameter for you is its performance in multi-threaded mode. In this mode, the processor uses all threads and cores that it has to the maximum to reach maximum efficiency. You will find out 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. Since there are still many programs that can use only one core to work, and all the benefit of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most useful will be the the possibility of overclocking it and release date of the processor. The newer the processor, the longer it will last you. 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 even in new games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The economy are obvious!
