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 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, just look at the FPS that it produces in real games in the summary table below.
List of other games in which processors were compared: Monster Hunter World, Ghostrunner, Hitman 3, Forza Horizon 4, Half-Life: Alyx, Shadow of the Tomb Raider, The Witcher 3: Wild Hunt, League of Legends (LOL), Battlefield V, Resident Evil 7 Biohazard, PlayerUnknown's Battlegrounds (PUBG), DOTA 2A, Counter-Strike: Global Offensive (CS GO), Horizon Zero Dawn, Microsoft Flight Simulator, Metro Exodus, Control, NBA 2K20.

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: 2K, FullHD or 4K. So 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 compare it in one assembly with the video card that is installed in your computer.

To make a final choice 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 Pentium Silver J5040 is more energy efficient than the Pentium Gold G6405U as it consumes less power: 10W vs. 15W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, you must 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

Let's say you want to use the processor not only for gaming, but also for machine learning, programming, streaming, video rendering or video editing, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum performance, the processor uses all cores and threads that it has. 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. Because there are still many programs that use only one core to run, and all the advantages 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 in your computer. And the easier it will be to upgrade the system later. The same benefits from the presence of overclocking. When the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS in the newest games. The economy are obvious! It turns out that you do not need to buy a new CPU to enjoy the games any longer.

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Pentium Gold G6405U is 16% better than Pentium Silver J5040 in terms of CPU frequency. Another difference is that Pentium Silver J5040 has 2 more core than Pentium Gold G6405U. Also keep in mind that high CPU frequency affects battery life through power consumption (relevant for laptops).

Result:
The number of parameters for which Intel Pentium Silver J5040 is better: 11
The number of parameters for which Intel Pentium Gold G6405U is better: 13
Although it should be understood that the summary data in the table above do not mean that taking them into account you should entirely trust a simple comparison of these numbers. Better to watch benchmarks video and read the opinion of of people who bought Intel Pentium Silver J5040 and Intel Pentium Gold G6405U before deciding which processor to buy for gaming and which not.
