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 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, 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 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 decision on which processor is better, you should also consider the generation of its core. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Core i9-10900KF is more energy efficient than the Core i9-7900X as it consumes less power: 140W vs. 125W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, it will be useful to 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

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

Comparison of specifications

In the specification comparison table, the most useful will be the the possibility of overclocking it and release date of the processor. The later the processor is released, the longer it will last you. And the easier it will be to upgrade the system in the future. 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 even in the newest games. The economy are obvious! Accordingly, you do not need to buy a new CPU to enjoy the games any longer.
