   From the video comparison, you can get the results of parallel examination in special testing software such as MATLAB, PassMark, WPrime, Blender, Gears 5, AIDA64, RealBench, DaVinci Resolve Studio, Blender, Dolphin Emulator, 7zip, Furmark, UserBenchmark, GeekBench 6, 5.2, Cinebench 23 (20, 15), PCMark 10, Prime95, SuperPi, Handbrake, World of Tanks enCore Benchmark, VeraCrypt, 3DMark.
   And how good the CPUs are in games:
  • Assassin's Creed Valhalla
  • Fortnite
  • Death Stranding
  • Fallout 76
  • DOOM: Eternal
  • Valheim
  • Red Dead Redemption 2
  • Overwatch

Summary benchmark results

As a percentage of the maximum value based on a sample from the entire base of all processors
Processor Benchmark
Core i5-8600K53% Core i5-940052%
This parameter shows the performance of the processors in single-threaded and multi-threaded mode. In this comparison, Core i5-8600K is 1% better than Core i5-9400. The data source is several popular tests. Detailed information can be found below.

Gaming performance
Summary result of all game benchmarks.
Core i5-8600K53% Core i5-940053%
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 run games. Because this processor costs several tens of thousands of dollars. And if it seems to you that the selected CPU has a low 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: Metro Exodus, DOTA 2A, Battlefield V, PlayerUnknown's Battlegrounds (PUBG), Counter-Strike: Global Offensive (CS GO), Forza Horizon 4, Ghostrunner, Shadow of the Tomb Raider, Resident Evil 7 Biohazard, The Witcher 3: Wild Hunt, Monster Hunter World, NBA 2K20, Hitman 3, Horizon Zero Dawn, Microsoft Flight Simulator, Half-Life: Alyx, League of Legends (LOL), Control.

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 i5-8600K41% Core i5-940056%
To make a finishing 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 i5-9400 is more energy efficient than the Core i5-8600K as it consumes less power: 95W vs. 65W. Power consumption is particularly important for laptops. Also, when choosing a processor cooling system, it will be useful to know its TDP. 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

For example you want to use the processor not only for gaming, but also for streaming, programming, machine learning, video editing or video rendering, then first of all you need to pay attention to the performance in multi-threaded mode. In this mode, the CPU includes all threads and cores that it has to the maximum to reach maximum efficiency. 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 work, and all the benefit 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 in the future. The same can be said about overclocking. If the processor can be overclocked, thereby increasing its performance, then it will still be able to produce 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!

In this comparison block, you should pay attention to the differences in clock speed and the number of cores. Here Core i5-8600K is 19% better than Core i5-9400 in terms of CPU frequency. 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 i5-8600K is better: 22
The number of parameters for which Intel Core i5-9400 is better: 6
   Although it should be realized that all the figures in the table above do not mean that you should be guided entirely by them and trust a simple comparison of these figures. Better to watch the testing video and read the reviews of real owners of Intel Core i5-8600K and Intel Core i5-9400 before deciding which of the processors to buy for gaming.
