We can better compare what are the technical differences between the two processors.
Suggested PSU: We assume that we have An ATX computer case, a high end graphics card, 16GB RAM, a 512GB SSD, a 1TB HDD hard drive, a Blu-Ray drive. We will have to rely on a more powerful power supply if we want to have several graphics cards, several monitors, more memory, etc.
Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.
We see that the two processors have an equivalent number of cores, the maximum frequency of Intel Core i5-8600K is greater, that the thermal dissipation power of Intel Core i5-9400F is less. The Intel Core i5-9400F was started more recently.
Performances :
Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench 4.

i5-8600K
- In some games, a processor with a higher clock speed, or with the technical name IPC (Instructions per clock), performs better than other processors with more cores and a lower core frequency.
- The i5-8600K has a higher turbo clock. Turbo Boost is a processor feature that will run at a processor clock speed faster than its base clock speed if certain conditions are present. This will allow older software that runs on fewer cores to run better on newer hardware. Since games are also software, they are also applicable.
i5-9400F
- i5-9400F i5-9 processor400F is more energy efficient and generates less heat.
