Intel Core i7-8086K

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.

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.
