To find out if there are any performance improvements due to architectural changes, we limit the clock speeds of our test suite processors to a mere 4GHz. In fact for our Core i7-7700K we had to down clock it to make the  Instructions Per Clock comparison (IPC) happen.

Let us start off with a single threaded benchmark, being again our beloved SuperPi 32M. A benchmark relying heavily on bandwidth combined with CPU speed. With all our processors clocked at the same speed it will become more clear if the new Kaby Lake CPU generation has a gain over its predecessors.

Mmm okay we are seeing no specific performance improvement here. So is Intel pulling off another Devils Canyon on us? Time to verify our initial finding with the other benchmarks in the test suite.

Well hate to bust the bubble, Cinebench Release 15 shows a similar score as the Sky lake generation. No IPC improvement to be spotted here, so performance wise Kaby Lake is a solid clock boost over the previous generation, but don't look for further architectural improvements besides the much improved encoding/decoding capabilities of the HD 630 iGPU.

And it continues, no matter the benchmark or game we throw at the brand new Core i7-7700K, clock per clock it performs the same as the previous Sky Lake generation.
