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 the cost of this processor reaches several tens of thousands of dollars. Therefore, if you think 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 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 i5-11400H is more energy efficient than the Core i9-12900KS since it has less power consumption: 150W vs. 45W. 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 video editing or video rendering, machine learning, programming, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU turns on all cores and threads that it has to the maximum to achieve maximum efficiency. 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 can 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 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.
