INTEL KABY LAKE
Compared with the Core i7-6700K, not much has changed with the release of the 7700K, other than a clock speed bump, improved 4K video playback and a few optimisations. Both CPUs use the same 14nm manufacturing process, both are quad-core, Hyper-Threaded CPUs and both have 8MB of Level 3 cache with a 91W TDP. Indeed, forcing both CPUs to run at 4GHz sees
identical results in Cinebench R15. The most significant changes are in the default clock speeds. The base clock has risen from 4GHz to 4.2GHz and the turbo frequency now stands at 4.5GHz, up from 4.2GHz. This difference accounts for the advantage seen at stock speed in our graphs, but that’s largely irrelevant for enthusiasts with an over clockable K-series CPU.
