The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

A decent CPU, however, stuck inside the smaller chassis of the Alienware 15 R3 (2017) it continually thermal throttles. This makes the main positive aspect of this chip, being unlocked, pretty much useless as the temperatures will rise too much for overclocking to be useful. Even without overclocking this chip runs very hot. Only recommended for 17 inch sized laptops.  [Dec '19 ThreeAreLeft]
