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

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.
Power consumption

Core i7-8559U | 123% |
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 Core i7-8559U is more energy efficient than the Core i5-9400T since it has less power consumption: 35W vs. 28W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you need 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 benchmarksLet's say you plan to use the processor not only for gaming, but also for streaming, machine learning, video rendering or video editing, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum efficiency, the CPU turns on all threads and cores that it has. You will find out this data from the benchmark tables below. Before using the data from these tests, be sure to find out whether the software that you are going to use on your computer can work in multi-threaded mode. Since there are still many programs that use only one core to work, and all the advantages of multi-core mode are unused.

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 later the processor is released, the longer it will last in your computer. And the easier it will be to upgrade the system in the future. The same benefits from the presence of overclocking. When the processor can be overclocked, thereby increasing its performance, then it will continue to maintain maximum FPS in new games. Accordingly, you do not need to buy a new CPU to enjoy the games any longer. The savings are obvious!
