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. And if it seems to you 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: NBA 2K20, Forza Horizon 4, Control, League of Legends (LOL), Hitman 3, Horizon Zero Dawn, Battlefield V, DOTA 2A, Resident Evil 7 Biohazard, Metro Exodus, Ghostrunner, Half-Life: Alyx, Counter-Strike: Global Offensive (CS GO), The Witcher 3: Wild Hunt, Microsoft Flight Simulator, Monster Hunter World, Shadow of the Tomb Raider, PlayerUnknown's Battlegrounds (PUBG).

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 tested computers not only did they have different video cards and different amounts of RAM. But users also tested them at different screen resolutions: FullHD, 2K or 4K. 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 compare it in one assembly with the video card that is installed in your computer.

To make a final 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 Pentium Silver J5040 is more energy efficient than the Core i5-6400 since it has less power consumption: 10W vs. 65W. 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

For example you want to use the processor not only for gaming, but also for programming, video rendering or video editing, streaming, machine learning, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to achieve maximum efficiency, the CPU includes all threads and cores 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 can 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 processor release date and overclocking capability will be the most helpful. 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, 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.
