Notes
It's worth mentioning that the Core i7-8086K doesn't behave exactly like the Core i7-8700K at default speeds when set to auto configuration in the BIOS. The former chip runs at a solid 4.3GHz all-core speed under all benchmarks, while the Core i7-8700K moves around from an all-core 4.1GHz (on long-duration, predominantly AVX benchmarks) to 4.3GHz (on short-duration benchmarks). This is why you will see slightly different results for both stock-clocked processors in the upcoming graphs.
When running at the 5.0GHz all-core speed mentioned on the previous page, we also increased the memory speed to 3,200MHz with 14-14-14 timings, to better reflect what an enthusiast is likely to do.
