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.
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.
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.
