For the maximum in this test, the results of the most powerful processor in the site database are taken. And it is clear that 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 little 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 tested computers not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, 4K or FullHD. Therefore, 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 get acquainted with the benchmarks that are made with the same 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. The newer the processor generation, the better its performance in games and benchmarks, as well as its energy efficiency. In this case the Core i5-12400T is more energy efficient than the Core i9-12900KF as it consumes less power: 125W vs. 35W. Power consumption is particularly 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

For example you want to use the processor not only for gaming, but also for streaming, programming, video rendering or video editing, machine learning, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the processor includes all cores and threads 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 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 advantages of multi-core mode turns out to be unnecessary.

Comparison of specifications

In the specification comparison table, the processor release date and overclocking capability will be the most useful. The newer the processor, 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. When the processor can be overclocked, thereby increasing its performance, then it will still be able to produce maximum FPS even in new games. The economy are obvious! Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer.
