Intel Core i9-9900K vs Intel Core i5-9400F

Intel Core i9-9900K

► remove from comparison

The Intel Core i9-9900K is a high end desktop processor based on the Coffee Lake architecture. At the time of announcement in late 2018, the 9900K is the fastest Coffee Lake CPU and offers an open multiplicator for easy overclocking. The CPU integrates 8 cores (16 threads) clocked at 3.6 - 5 GHz and it needs a new Z390 based mainboard.

Thanks to the two additional cores, the performance in multi-threaded applications is up to 25 % faster than the older Core i7-8700K. The single thread performance is only slightly faster due to the higher clock speeds. As a high end desktop CPU, the i9-9900K 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 i5-9400F

► 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.
