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

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 tested computers not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, FullHD 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 compare it in one assembly with the video card that is installed in your computer.

To make a finishing 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 i7-11700B is more energy efficient than the Core i9-13900K since it has less power consumption: 125W vs. 65W. Power consumption is especially important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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

Let's say you want to use the processor not only for gaming, but also for machine learning, programming, streaming, 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 includes 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 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 use only one core to run, and all the benefit of multi-core mode are unused.

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 later the processor is released, 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. If the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS even in new games. The savings are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.
