Intel Core i7-9700K vs Intel Core i5-8600K vs Intel Core i5-9400F

Intel Core i7-9700K

► remove from comparison Intel i7-9700K

The Intel Core i7-9700K is a high end desktop processor based on the Coffee Lake architecture. It offers an open multiplicator for easy overclocking and integrates 8 cores (no Hyperthreading therefore also 8 threads) clocked at 3.6 - 4.9 GHz and it needs a new Z390 based mainboard.

Thanks to the two additional cores, the performance in multi-threaded applications is even better than the old Core i8-8700K with 6 cores and Hyperthreading. As a high end desktop CPU, the i9-9700K is suited even for very demanding applications and perfect for 3D gaming.

The integrated Intel UHD Graphics 630 graphics card is clocked at up to 1.2 GHz and offers no advantage compared to previous generations. As it is a very low end GPU, only some low demanding games like Hearthstone can be played with it (see GPU page for benchmarks).

Intel specifies the TDP at 95 Watt, so if the CPU is used in laptops a big and chunky cooling system is needed to avoid throttling and lower clock speeds under sustained loads. When overclocking the CPU, the power consumption can easily rise up to 200 Watt and higher.

Intel Core i5-8600K

► remove from comparison Intel i5-8600K

The Intel Core i5-8600K is a high-end desktop processor with six cores based on the Coffee Lake architecture and was announced in September 2017. The processor clocks at between 3.6 and 4.3 GHz and can execute up to six threads simultaneously (no HyperThreading). According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. The i5-8600K is comparatively easy to overclock thanks to the unlocked multiplier.

Performance

Due to the two additional cores, performance has increased significantly compared to the Core i7-7700K when all cores are in use. Single-core performance has not improved since its Kaby Lake predecessor. As a high-end model, the i5-8600K is suitable for the most demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is basically identical to the previous generation Intel HD Graphics 630. Only some low demanding games are playable with this graphics card (see GPU page linked above).

Power Consumption

Intel specifies the TDP with 95 watts. Therefore, well-dimensioned cooling systems should easily manage to deal with the created heat. We expect increased efficiency due to the higher performance.

Intel Core i5-9400F

► remove from comparison Intel i5-9400F

The Intel Core i5-9400F is a six-core desktop processor based on the Coffee Lake architecture introduced in October 2018 along with the flagship Intel Core i9-9900K. The processor clocks at 2.9-4.1 GHz and can process up to 6 threads simultaneously. The Intel Core i5-9400F is manufactured in the improved 14-nm process (14nm++).

Performance

Compared to the Intel Core i5-8400, the performance could only be increased slightly. Performance increases of up to 10 percent can be expected. Both processors (old and new) still do not offer hyperthreading. The performance increase therefore only adds up to small architecture improvements and a slightly higher basic and turbo clock rate. This CPU is suitable for everyday office use, which does not require large coolers due to the low waste heat. But games are also among the application areas, because in games the Intel Core i5-9400F clearly beats the Intel Core i3-9100F. Here the six cores are paying off in the meantime. 

Graphics unit

The Intel Core i5-9400F is a processor without integrated graphics unit. If you value an iGPU, you should take a closer look at the Intel Core i5-9400, as it offers the entry level Intel UHD Graphics 630.

Power consumption

Intel puts the Thermal Design Power (TDP) at 65 watts. This means there is no need for large cooling systems, which also allows installation in very compact housings.
