Core i5-8400T | 52% |
The maximum result in this parameter is 100 percent, which is the performance of the most powerful processor currently available. 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. Therefore, if you think that the selected CPU has a low game result, look at the FPS that it produces in real games in the final table below.
List of other games in which processors were compared: Horizon Zero Dawn, Forza Horizon 4, Metro Exodus, Hitman 3, The Witcher 3: Wild Hunt, NBA 2K20, DOTA 2A, Ghostrunner, Monster Hunter World, Microsoft Flight Simulator, Resident Evil 7 Biohazard, League of Legends (LOL), Counter-Strike: Global Offensive (CS GO), Control, Battlefield V, Shadow of the Tomb Raider, Half-Life: Alyx, PlayerUnknown's Battlegrounds (PUBG).
Gaming benchmark| Fortnite | 91.6 | 92.6 | | Valorant | 104.1 | 105.2 | | Cyberpunk 2077 | 58.3 | 58.9 | | Apex Legends | 97.8 | 98.9 | | Call of Duty Warzone | 78.1 | 78.9 | | Overwatch | 84.3 | 85.2 | | Red Dead Redemption 2 | 71.8 | 72.6 | | DOOM Eternal | 52.0 | 52.6 | | Warzone | 81.2 | 82.1 | | Assassin's Creed | 87.4 | 88.4 | | Valheim | 86.4 | 87.3 |
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 that were in the comparisons not only did they have different amounts of RAM and different video cards. But users also tested them at different screen resolutions: 2K, 4K or FullHD. Therefore, 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 i7-8665UE | 240% |
Core i5-8400T | 91% |
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 i7-8665UE is more energy efficient than the Core i5-8400T since it has less power consumption: 15W vs. 35W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, it will be useful to know its TDP. You need to buy a cooler that has the TDP data specified in the specification was greater than the TDP of the compared processor.
Software benchmarksFor example you want to use the processor not only for gaming, but also for video rendering or video editing, machine learning, programming, streaming, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, to reach maximum efficiency, the processor uses 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 make sure that 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 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.
