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 small game result, 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 comparisons not only were the equipped with different video cards and different amounts of RAM. But users also tested them at different screen resolutions: 2K, FullHD or 4K. 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. 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 i9-12900 is more energy efficient than the Ryzen Threadripper PRO 3945WX as it consumes less power: 65W vs. 280W. Power consumption is especially 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

If you plan to use the processor not only for gaming, but also for programming, streaming, video editing or video rendering, machine learning, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU turns on all threads and cores that it has to the maximum to achieve maximum efficiency. 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. Because there are still many programs that 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 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 can be said about overclocking. If the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS in new games. Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer. The savings are obvious!
