Intel Core i5-9400F vs Intel Core i7-9700 vs Intel Core i5-9600K
Intel Core i5-9400F► remove from comparison
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++).
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.
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.
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.
Intel Core i7-9700► remove from comparison
The Intel Core i7-9700 is a high end desktop processor based on the Coffee Lake architecture. It integrates 8 cores (no Hyperthreading therefore also 8 threads) clocked at 3 - 4.7 GHz. Compared to the similar named Core i7-9700K, the 9700 has no open multiplicator for easy overclocking, offers lower clock speeds and offers a reduced TDP.
Compared to the old Core i7-8700, the 9700 offers two more real cores but no Hyperthreading. Therefore, the performance gain is not that big - depending on the app. The single core performance was slightly improved thanks to the higher Turbo clocks. As a high end desktop CPU, the i7-9700 is well suited for demanding tasks and 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 65 Watt (instead of the 95W of the faster models) and therefore the CPU wont need a high end desktop cooling system.
Intel Core i5-9600K► remove from comparison
The Intel Core i5-9600K is a high end desktop processor based on the Coffee Lake architecture. It offers an open multiplicator for easy overclocking and integrates 6 cores (no Hyperthreading therefore also 6 threads) clocked at 3.7 - 4.6 GHz and it needs a new Z390 based mainboard. It is manufactured in the second iteration of the improved 14nm process (14nm++).
Compared to the older Core i5-8600K, the 9600K offers about 10 to 15% higher performance. As the CPU still offers 6 cores and threads, the improvements are mostly due to the higher clock speeds. As a fast mid range desktop CPU, the i5-9600K 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 1.15 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 150 Watt and higher.
