Core i7-8086K


Description
We need your help: we don't have results in all modes. If you have a i7-8086K and want to help us to complete the stats, you just have to run the benchmark at stock frequency (no oc) in modes FPU, SSE, AVX, and validate the results. You don't have to register and the whole process will take less than 3 minutes per mode.

The Core i7-8086K is a cpu manufactured by Intel that was released on June 2018. This model has 6 Coffee Lake-S cores with HyperThreading, runs at 4000 MHz as base frequency and has a a thermal design power of 95 W.

The i7-8086K has 6x32+6x32 kB of cache L1, 6x256 kB of cache L2 and 12288 kB of cache L3.

Coffee Lake is the second refinement of Intel’s 14nm (Tri-Gate) technology. While it uses LGA1151 socket, it is incompatible with previous generations due to electrical changes in socket’s pins so these CPUs require Z370 chipset. This kind of generation introduced more cores in every range to compete with new AMD’s architecture. Coffee Lake uses DDR4 memory at 2400MHz for i3 and at 2666MHz for i5, i7 CPUs plus iGPU frequency has been increased 50MHz with respect to previous generation.

AVX2 optimized benchmark
The benchmark in mode III (AVX2), like AVX1, is optimized to used 256 bits registers beside the second version of the Advanced Vector Extensions (AVX). The first AVX2 compatible CPU was released in 2013.

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.

Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.

If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
