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

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. 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 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 i7-6700K is more energy efficient than the Ryzen 5 2400G as it consumes less power: 95W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, it will be useful to know its TDP. 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 plan to use the processor not only for gaming, but also for video editing or video rendering, streaming, programming, machine learning, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum performance, the CPU uses all threads and cores that it has. You will learn this data from the benchmark tables below. Before you take into account 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 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.
