Intel Core i7-8700K and i5-8400 Coffee Lake CPU Review (Page 3)

Check out those CINEBENCH and wPrime scores. Since Coffee Lake is Kaby Lake on core and frequency steroids, we expected to find linear scaling between the Intel parts. We also find out that the 8700K's 4.7GHz single-core Turbo makes it the fastest single core processor in our charts, a title previously held by the 7700K. We can also see that without the mesh and with Intel's Skaylake/Kaby Lake/ Coffee Lake Core microarchitecture (they are all pretty much similar) on a ring bus, Intel is fighting the competition on the performance side while the competition hits back with price/performance.

AIDA64 FPU results reveal Intel's floating point strength, but also highlight AMD's strong IOPS performance. That i5-8400 is also a bit of a surprise, and we will see it surprise a bit more in the following pages. Memory bandwidth and latency haven't really changed going from 7th to 8th generation.
