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

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 comparing not only were the equipped with different video cards and different amounts of RAM. But users also tested them at different screen resolutions: FullHD, 2K or 4K. Therefore, 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 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 i7-6700 is more energy efficient than the Core i5-3570K since it has less power consumption: 77W vs. 65W. 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 streaming, video rendering or video editing, programming, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, to achieve maximum performance, the CPU turns on all cores and threads 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 software you are going to use on your computer supports multi-threaded mode. Because there are still many programs that use only one core to run, and all the advantages of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most helpful 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 in the future. The same benefits from the presence of overclocking. When the processor can be overclocked, thereby increasing its performance, then it will still be able to produce maximum FPS even in the newest games. The savings are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which Intel Core i5-3570K is better: 0
The number of parameters for which Intel Core i7-6700 is better: 32
However, it should be understood that all the data in the article above do not mean that taking them into account you should fully trust a simple quantitative comparison. Better to watch the testing video and read the opinion of of people who bought Intel Core i5-3570K and Intel Core i7-6700 before making a decision which of the processors to buy for gaming.
