There now are several reviews posted on Kaby lake Core i7 7700K. There is a new one though, and this is the first being tested with the new Intel Z270 chipset.

The results originate from Expreview. The Kaby lake platform for desktops will support USB 3.1 and DDR4. The specs of Intel Core i7 7700K Kaby Lake processor surfaced in the SiSoft SANDRA benchmark results page. The Core i7 7700K listed is once again a quad-core with HyperThreading enabling 8 logical CPUs.

Kaby Lake
Model	Cores/Threads	Cache	Baseline Frequency	Max Turbo Boost	TDP	IGP
Core i7-7700K	4/8	8MB	4.20 GHz	4.50 GHz	95W	630
Core i5-7600K	4/4	6MB	4.00 GHz	4.20 GHz	95W	630

Expreview used the processor on an Gigabyte Z270 as you can tell from a photo at the last page of their review. The CPU clocks in at a 4.20GHz core frequency with 4.50GHz max turbo boost with a TDP of 95W. That's 100 More then a i7-6700K's 91W. Overall you are looking at a 9% multi-threaded performance increase over the Core i7 6700K, mainly due to the higher turbo clocks.

Expreview also posted a clock for clock chart, both processors clocked at 4.0 GHz on all cores. Then the performance difference is -0.02% Check out the thumbnails for the results.
