The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. 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. Therefore, if you think that the selected CPU has a small game result, look at the FPS that it produces in real games in the summary table below.
List of other games in which CPU comparisons were performed: Resident Evil 7 Biohazard, League of Legends (LOL), Battlefield V, Metro Exodus, Hitman 3, The Witcher 3: Wild Hunt, DOTA 2A, PlayerUnknown's Battlegrounds (PUBG), Half-Life: Alyx, Control, Monster Hunter World, Horizon Zero Dawn, Shadow of the Tomb Raider, Ghostrunner, Forza Horizon 4, Microsoft Flight Simulator, Counter-Strike: Global Offensive (CS GO), 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 get acquainted with the benchmarks that are made with the same video card that is installed in your computer.


Power consumption
Core i5-8257U235% Core i5-8400T91%
To make a finishing resolution 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 i5-8257U is more energy efficient than the Core i5-8400T as it consumes less power: 15W vs. 35W. Power consumption is particularly important for laptops. And TDP should be taken into account when choosing a processor cooling system. 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 benchmarks

Let's say you plan to use the processor not only for gaming, but also for machine learning, programming, streaming, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum performance, the processor includes all threads and cores 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 software you are going to use on your computer supports multi-threaded mode. Since there are still many programs that can 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 useful will be the the possibility of overclocking it and release date of the processor. The later the processor is released, 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. If the processor can be overclocked, increasing its performance, then it will continue to maintain maximum FPS in new games. The economy are obvious! Accordingly, 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 Core i5-8400T is 17% better than Core i5-8257U in terms of CPU frequency. Another difference is that Core i5-8400T has 2 more core than Core i5-8257U. 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 Core i5-8257U is better: 11
The number of parameters for which Intel Core i5-8400T is better: 21
   Although it should be understood that all the data in the article above do not mean that taking them into account you should completely trust a simple comparison of these numbers. Better to watch the video tests and read the reviews of of people who bought Intel Core i5-8257U and Intel Core i5-8400T before making a decision which of the processors to buy for gaming.
