The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. And of course, 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.

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 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. 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 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 i5-7400 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 plan to use the processor not only for gaming, but also for machine learning, streaming, programming, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU uses all threads and cores that it has to the maximum to achieve maximum performance. You will find out this data from the benchmark tables below. Before you take into account the data from these tests, be sure to find out whether 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 work, and all the benefit of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most useful. 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 can be said about overclocking. When the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS in the newest games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The economy are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i5-3570K is 11% better than Core i5-7400 in terms of CPU frequency. 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: 12
The number of parameters for which Intel Core i5-7400 is better: 14
The summary data that you have looked at here do not mean that taking them into account you should completely trust a simple quantitative comparison. Better to watch the testing video and read the reviews of real owners of Intel Core i5-3570K and Intel Core i5-7400 before making a selection which CPU to buy for gaming and which not.
