The Core i7-2700K is a 3.5GHz Sandy Bridge processor. Sporting four cores and eight threads the 2700K has a strong performance profile, even by today's standards. Comparing the 2700K and the 4770K shows that although the 4770K is two generations and nearly two years newer there is still only around 7% separating the processors in terms of overall calculation throughput. The 4770K does have a 12% lower TDP and it's also compatible with Intel's latest platform so as a new purchase it is the clear winner, but owners of the 2700K are only missing out on marginally better performance. [Mar '14 CPUPro]

MORE DETAILS

The i5-7600K targets high end gamers, it sits just behind the flagship i7-7700K in Intel’s Kaby Lake lineup. The 7600K will likely be the most popular gaming CPU of 2017 (some competition from AMD’s upcoming Zen/Ryzen CPUs, would be very welcome). Comparing the 7600K and 6600K shows that the two processors are very closely matched and comparing the 7600K vs the hyper-threaded 7700K highlights the relative strength of the 7700K for workstation performance. There are no significant architectural differences between Kaby Lake and Skylake so, when fully overclocked, the two generations should perform similarly but Kaby Lake offers faster base clocks, improved speed shift technology which helps CPU responsiveness, and better integrated graphics[Jan '17 CPUPro]
