The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. And it is clear that 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 small 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: Microsoft Flight Simulator, Forza Horizon 4, Shadow of the Tomb Raider, Half-Life: Alyx, Ghostrunner, PlayerUnknown's Battlegrounds (PUBG), Battlefield V, Monster Hunter World, League of Legends (LOL), Horizon Zero Dawn, Hitman 3, The Witcher 3: Wild Hunt, Control, NBA 2K20, Metro Exodus, Counter-Strike: Global Offensive (CS GO), DOTA 2A, Resident Evil 7 Biohazard.

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 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 i5-8400 is more energy efficient than the Core i5-10600K since it has less power consumption: 125W vs. 65W. 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 programming, machine learning, streaming, video rendering or video editing, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum performance, the processor turns on all cores and threads that it has. 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 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 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.
