The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor at the moment. And it is clear that this is a server processor, on which no one will play 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 small game result, just look at the FPS that it produces in real games in the final table below.
List of other games in which processors were compared: Battlefield V, Forza Horizon 4, Microsoft Flight Simulator, Hitman 3, Shadow of the Tomb Raider, Counter-Strike: Global Offensive (CS GO), Metro Exodus, DOTA 2A, League of Legends (LOL), Monster Hunter World, PlayerUnknown's Battlegrounds (PUBG), The Witcher 3: Wild Hunt, Half-Life: Alyx, Ghostrunner, NBA 2K20, Control, Horizon Zero Dawn, 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 comparing not only were the equipped with different video cards and different amounts of RAM. 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. 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.
Power consumption
| Core i5-9400T | 91% |
Core i5-8257U | 235% |
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 i5-8257U is more energy efficient than the Core i5-9400T as it consumes less power: 35W vs. 15W. Power consumption is particularly 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 benchmarksIf you plan to use the processor not only for gaming, but also for programming, video rendering or video editing, machine learning, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the processor turns on all cores and threads that it has to the maximum to achieve maximum performance. You will learn this data from the benchmark tables below. Before you take into account the data from these tests, be sure to make sure that the program 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!
