Intel Core i7-8700K vs Intel Core i9-9900KS vs Intel Core i7-8086K

Intel Core i7-8700K

► remove from comparison Intel i7-8700K

The Intel Core i7-8700K 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 3.7 and 4.7 GHz and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. The i7-8700K is comparatively easy to overclock thanks to the unlocked multiplier.

Performance

Due to the two additional cores, performance has increased by almost 50% 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 i7-8700K is suitable for the most demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer higher performance as its clock rate has been increased by 50 MHz. The build is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

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 i9-9900KS

► remove from comparison Intel i9-9900KS

The Intel Core i9-9900KS is a high end desktop processor that includes 8 cores based on the Coffee Lake architecture. It is the fastest Coffee Lake CPU in 2019 and compared to the similar named i9-9900K, the KS offers an all core Turbo of 5 GHz. All cores can clock between 4 GHz and 5 GHz and thanks to Hyperthreading / SMT 16 threads can be executed in parallel. The CPU is still manufactured in the mature 14 nm process (14nm++). Thanks to the open multiplicator, the CPU is rather easy to overclock (if a Z390 based mainboard is used).

With good cooling, the i9-9900KS can be around 10% faster than the older Intel Core i9-9900K (thanks to the 5 GHz all core Turbo). Compare to the old Core i7-8700K, the 9900KS is even 45% faster. Especially for gaming, the 9900KS is currently the fastest option available. The fast Ryzen and Threadripper CPUs from AMD however offer a better multithreaded performance.

The integrated GPU is called Intel UHD Graphics 630 and clocks with up to 1.2 GHz. It is not suited for demanding 3D games and located in the low end.

The TDP is raised to 127 Watt for the additional performance, therefore a good CPU cooler is needed. When overclocking the CPU, more than 200 Watt can be reached unter load.

Intel Core i7-8086K

► remove from comparison Intel i7-8086K

The Intel Core i7-8086K is a high-end desktop processor with six cores based on the Coffee Lake architecture and was announced in mid 2018. It is a limited edition for the 40 year X86 anniversary and at the time of announcement the fastest Coffee-Lake CPU. The processor clocks at between 3.7 and 5 GHz and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. The i7-8086K is comparatively easy to overclock thanks to the unlocked multiplier. Compared to the cheaper i7-8700K (-66 Dollars) only the single core Turbo clock speed is faster (5 GHz versus 4.7 GHz).

Performance

Due to the two additional cores, performance has increased by almost 50% compared to the Core i7-7700K when all cores are in use. Compared to the cheaper Core i7-8700K, the 8086K offers only a higher single core Turbo Boost and therefore in daily usage and gaming not faster. As a high-end model, the i7-8086K is suitable for the most demanding applications and games.
