The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. 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 low 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 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. 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 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 Ryzen 7 5800U is more energy efficient than the Ryzen 9 3950X as it consumes less power: 20W vs. 105W. 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

For example you want to use the processor not only for gaming, but also for video editing or video rendering, machine learning, streaming, programming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum performance, the processor turns on all threads and cores that it has. You will learn this data from the benchmark tables below. Before using the data from these tests, be sure to check whether the software you are going to use on your computer supports multi-threaded mode. Because there are still many programs that use only one core to run, and all the benefit of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most useful will be the release date of the processor and the possibility of overclocking it. 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 can be said about overclocking. If the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS in the newest games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The savings are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Ryzen 9 3950X is 45% better than Ryzen 7 5800U in terms of CPU frequency. Another difference is that Ryzen 9 3950X has 8 more core than Ryzen 7 5800U. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which AMD Ryzen 7 5800U is better: 4
The number of parameters for which AMD Ryzen 9 3950X is better: 29
However, it should be realized that all the figures that you have looked at here do not mean that you should be guided entirely by them and trust a simple quantitative comparison. Better to watch the video tests and read the reviews of of people who bought AMD Ryzen 7 5800U and AMD Ryzen 9 3950X before making a decision which of the processors to buy for gaming.
