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. And if it seems to you that the selected CPU has a small 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 that were in the comparisons not only did they have different video cards and different amounts of RAM. 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 get acquainted with the benchmarks that are made with the same video card that is installed in your computer.

To make a finishing decision 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 Ryzen 9 3900 is more energy efficient than the Ryzen 7 7800X3D as it consumes less power: 120W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you must know its TDP. 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

If you want to use the processor not only for gaming, but also for machine learning, streaming, video rendering or video editing, programming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the processor turns on all threads and cores 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 check whether the program you are going to use on your computer supports multi-threaded mode. Since there are still many programs that use only one core to run, and all the advantages of multi-core mode are unused.

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 later the processor is released, 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. If the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS even in new games. The savings are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.
