Summary benchmark resultsAs a percentage of the maximum value based on a sample from the entire base of all processors
Processor Benchmark
| Core i5-6600K | 51% |
Core i5-8400 | 52% |
This parameter shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Core i5-8400 is 1% better than Core i5-6600K. The data source is several popular tests. Detailed information can be found below.
Gaming performance
Summary result of all game benchmarks.| Core i5-6600K | 52% |
Core i5-8400 | 53% |
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 play games. Because this processor costs several tens of thousands of dollars. Therefore, if you think that the selected CPU has a little game result, look at the FPS that it produces in real games in the final table below.
List of less popular games in which CPU comparisons were performed: The Witcher 3: Wild Hunt, PlayerUnknown's Battlegrounds (PUBG), Control, League of Legends (LOL), Resident Evil 7 Biohazard, Half-Life: Alyx, NBA 2K20, Ghostrunner, Battlefield V, Counter-Strike: Global Offensive (CS GO), Forza Horizon 4, DOTA 2A, Shadow of the Tomb Raider, Metro Exodus, Horizon Zero Dawn, Monster Hunter World, Hitman 3, Microsoft Flight Simulator.
Gaming benchmark| Fortnite | 92.9 | 93.5 | | Valorant | 105.5 | 106.3 | | Cyberpunk 2077 | 59.1 | 59.5 | | Apex Legends | 99.2 | 99.9 | | Call of Duty Warzone | 79.1 | 79.7 | | Overwatch | 85.5 | 86.1 | | Red Dead Redemption 2 | 72.8 | 73.3 | | DOOM Eternal | 52.8 | 53.1 | | Warzone | 82.3 | 82.9 | | Assassin's Creed | 88.6 | 89.3 | | Valheim | 87.6 | 88.2 |
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: 2K, FullHD or 4K. 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 get acquainted with the benchmarks that are made with the same video card that is installed in your computer.
Power consumption
| Core i5-6600K | 51% |
Core i5-8400 | 56% |
To make a finishing choice 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 i5-8400 is more energy efficient than the Core i5-6600K as it consumes less power: 91W vs. 65W. Power consumption is especially important for laptops. Also, when choosing a processor cooling system, you must know its TDP. 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 benchmarksFor example you plan to use the processor not only for gaming, but also for video editing or video rendering, machine learning, programming, streaming, then the main parameter for you is its performance in multi-threaded mode. In this mode, the CPU turns on all cores and threads that it has to the maximum to achieve maximum efficiency. 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 can 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 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!
