An early CPU-Z test run backs this assumption. The Core i7-8700K scored 525.4 points in the benchmark's single-core test, outpacing the Core i7-7700K at 492 points.

Intel Core i5-8400 CPU-Z Processor And Cache Details The Core i5-8400 features the same physical die, but has only 9MB of Smart Cache enabled and Hyper-Threading has been disabled.

For $303, the i7-8700’s base clock matches the Turbo Boost speed of the Broadwell-E Core i7-6800K, and its Turbo speeds go all the way up to a very impressive 4.6 GHz.

Once overclocked, though, the Core i7-8700K managed to come within spitting distance of the AMD eight-core CPUs, which is a decent effort, while it also beat the Core i7-7800X at both settings ...

The i7 875K's memory performance is what you would expect from an 1156 i7. ... Now, on the same air cooling we are hitting 4.5GHz for CPU-Z shots and stable performance at 4.1GHz.
