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

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 amounts of RAM and different video cards. But users also tested them at different screen resolutions: FullHD, 2K or 4K. 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 decision 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 Core i3-8145UE is more energy efficient than the Core i5-6400 since it has less power consumption: 15W vs. 65W. 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 calculate so that the TDP data specified in the cooler specification is greater than the TDP of the compared processor.

Software benchmarks

If you plan to use the processor not only for gaming, but also for machine learning, video editing or video rendering, streaming, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum efficiency, the processor turns on all cores and threads 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 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 work, and all the benefit of multi-core mode are unused.

Comparison of specifications

In the specification comparison table, the most useful will be the the possibility of overclocking it and release date of the processor. 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. When the processor can be overclocked, increasing its performance, then it will still be able to produce maximum FPS in the newest games. The economy are obvious! Accordingly, there is no longer a need to buy a new CPU to enjoy the games any longer.
