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. 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.

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 that were in the comparisons not only did they have 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. 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 i5-11600 is more energy efficient than the Core i7-7820X since it has less power consumption: 140W vs. 125W. 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

For example you plan to use the processor not only for gaming, but also for programming, video rendering or video editing, streaming, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, the processor includes all threads and cores that it has to the maximum to reach maximum performance. You will find out this data from the benchmark tables below. Before using the data from these tests, be sure to make sure that the software that you are going to use on your computer can work in multi-threaded mode. Because there are still many programs that can 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 most helpful will be the release date of the processor and the possibility of overclocking it. The newer the processor, the longer it will last in your computer. And the easier it will be to upgrade the system later. The same benefits from the presence of overclocking. When the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS in the newest games. The economy are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.
