First up the stock impressions, without a doubt the brand new Kaby Lake series provide a decent performance increase over its predecessor. The Core i7-7700K running out of the box 200MHz higher clock speeds, versus the 4Ghz of the i7-6700K. Logically, the Turbo frequencies also were raised to 4.5GHz for the Core i7-7700K versus the maximum 4.2GHz Turbo of the Skylake i7-6700K.

Take note that we used the 2133MHz memory divider instead of the 2400MHz one (now officially supported by Intel)

In the single threaded SuperPi 32M, the new Core i7-7700K delivers the fastest quad core result on the chart. The Devils Canyon Core i7-4790K comes close as its Turbo is just 100MHz shy of the new Kaby Lake i7.

On the older Maxon Cinebench R10 the brand new 7700K quad core is battling it out with the high end hexacore brethren of the Haswell-E series; pretty remarkable as these have 2 extra cores to crunch with, though the newer versions again shows a strong performance versus any quad core on the market, but this time the higher core specced CPUs are logically pulling away in this multi-threaded benchmark. Without a doubt the Core i7-7700K is Intel's fastest mainstream processor to date.
