Today we can finally show some of our own results regarding the Core i7-8086K. A few months ago we have started testing all the recent CPUs regarding a variety of programs and benchmarks and meanwhile we’re starting to add Coffee Lake chips.

Our tests confirm what we've already seen with all the other leaks. At standard clock speeds and in the applications we've tested, the Core i7-8086K is on average 32% faster than the Core i7-5820K and 8% slower than the AMD Ryzen 7 2700X. If we set all the CPUs to 4.2 GHz then the Core i7-8086K is on average 13% faster than the Core i7-5820K and 10% slower than the AMD Ryzen 7 2700X. Overall the Core i7-8086K is slightly faster than the Core i7-8700K in single-threaded applications due to the higher turbo frequency.

In single-threaded applications with same clock speed, like for instance in "Black Hole", we can see that the Core i7-8086K is about 41% faster than the Core i7-5820K and 26% faster than the AMD Ryzen 7 2700X processors.

In addition we also ran a couple of benchmarks with our test sample pushed to 5.1 GHz at 1.33 volts on all cores. The benchmarks have been conducted on a Z370 motherboard with 4x4GB DDR4 memory. In combination with a Corsair H150i PRO RGB 360 CPU cooler the CPU reached 80°C quite quickly running Cinebench R15 and scoring 1'632 points. At the moment we haven't done any 3D tests but we are sure that the difference between Coffee Lake and Kaby Lake or Skylake will be tiny once again.
