The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. 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 little game result, just look at the FPS that it produces in real games in the summary table below.
List of less popular games in which CPU comparisons were performed: NBA 2K20, Control, Forza Horizon 4, PlayerUnknown's Battlegrounds (PUBG), Microsoft Flight Simulator, DOTA 2A, The Witcher 3: Wild Hunt, Ghostrunner, Hitman 3, Monster Hunter World, Horizon Zero Dawn, Counter-Strike: Global Offensive (CS GO), Battlefield V, Metro Exodus, Shadow of the Tomb Raider, Half-Life: Alyx, League of Legends (LOL), Resident Evil 7 Biohazard.

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 video cards and different amounts of RAM. 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 i5-9400T91% Core i7-8557U244%
To make a final resolution 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 i7-8557U is more energy efficient than the Core i5-9400T since it has less power consumption: 35W vs. 15W. 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

If you want to use the processor not only for gaming, but also for video editing or video rendering, streaming, machine learning, programming, then the main parameter for you is its performance in multi-threaded mode. In this mode, to reach maximum performance, the CPU includes 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 find out whether the software that you are going to use on your computer can work in multi-threaded mode. Because there are still many programs that use only one core to run, and all the benefit 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 in your computer. 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 still be able to produce 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!
