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]

The Intel Core i5-6600K is based on the new "Skylake" 14nm manufacturing process. Sporting 4 physical cores with base/turbo clocks of 3.5/3.9 GHz the 6600K and its predecessor, the 4690K share the same basic configuration and disappointingly, offer similar performance. Comparing the 6600K and 6700K shows that the 6700K has faster multi and single core performance. The improved multi core performance is due to Hyperthreading which is the key differentiator for the i7-6700K. The gap in single core performance can largely be eliminated by overclocking the i5-6600K so although the stock effective speed is significantly higher on the 6700K, this gap diminishes significantly when both processors are overclocked. At a 30% discount, the 6600K is the better value gaming CPU. [Aug '15 CPUPro]
