i5-9600K
- For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU’s with higher core count and lower core speed.
- The i5-9600K has a higher turbo clock boost. Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present. It will enable older software that runs on fewer cores, to perform better on newer hardware. Since games are software too, it is also applicable to them.
i5-8400
- The i5-8400 is more power efficient and generates less heat.
