Intel Core i5-7600K Tested, Negligible IPC Gains
Ahead of its launch, a Core i5-7600K processor (not ES) made its way to Chinese tech publication PCOnline, who wasted no time in putting it through their test-bench, taking advantage of the next-gen CPU support BIOS updates put out by several socket LGA1151 motherboard manufacturers. Based on the 14 nm "Kaby Lake" silicon, the i5-7600K succeeds the current i5-6600K, and could be positioned around the $250 price-point in Intel's product-stack. The quad-core chip features clock speeds of 3.80 GHz, with 4.20 GHz max Turbo Boost frequency, and 6 MB of L3 cache. Like all its predecessors, it lacks HyperThreading.
In its review of the Core i5-7600K, PCOnline found that the chip is about 9-10% faster than the i5-6600K, but that's mostly only due to its higher clock speeds out of the box (3.80/4.20 GHz vs. 3.50/3.90 GHz of the i5-6600K). Clock-for-clock, the i5-7600K is just about 1% faster, indicating that the "Kaby Lake" architecture offers only negligible IPC (instructions per clock) performance gains over the "Skylake" architecture. The power-draw of the CPU appears to be about the same as the i5-6600K, so there appear to be certain fab process-level improvements, given the higher clock speeds the chip is having to sustain, without a proportionate increase in power-draw. Most of the innovation appears to be centered on the integrated graphics, which is slightly faster, and has certain new features. Find more performance figures in the review link to PCOnline below.

We now have 51W Intel Cores with the single thread performance of earlier 2011/2012 Core CPUs overclocked @ 5.0GHz that have a TDP over 140W and a much higher voltage.
perhaps you should consider why Intel is going 6-core mainstream soon?
