For the maximum in this test, the results of the most powerful processor in the site database are taken. And of course, this is a server processor, on which no one will run games. Because this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a small game result, just 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 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. 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 choice 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 Ryzen 9 3900 is more energy efficient than the Ryzen 7 5700G since it has less power consumption: 65W vs. 65W. 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 want to use the processor not only for gaming, but also for programming, video editing or video rendering, machine learning, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU uses all threads and cores that it has to the maximum to reach maximum performance. You will find out 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. Because there are still many programs that can use only one core to work, and all the benefit of multi-core mode turns out to be unnecessary.

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 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. When 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 economy are obvious!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Ryzen 7 5700G is 16% better than Ryzen 9 3900 in terms of CPU frequency. Another difference is that Ryzen 9 3900 has 4 more core than Ryzen 7 5700G. 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 9 3900 is better: 23
The number of parameters for which AMD Ryzen 7 5700G is better: 8
However, it should be understood that all the data in the table above do not mean that taking them into account you should undividedly trust a simple quantitative comparison. Better to watch benchmarks video and read the opinion of of people who bought AMD Ryzen 9 3900 and AMD Ryzen 7 5700G before making a choice which CPU to buy for gaming and which not.
