The Intel Core i7-3770 is an Ivy Bridge processor. With four cores and eight threads the 3770 has excellent single , dual and multi-core performance. Comparing the 3770 to the 4770K shows that the 4770K leads by 11% at stock speeds and, thanks to an unlocked multiplier on the 4770K, by 15% at overclocked frequencies. The i7-3770 has a very strong performance profile which includes multi-core capabilities that are likely to be overkill for the majority of desktop users. Comparing the 3770 to the 3770K shows that the unlocked 3770K allows for, on average, an additional 8% increase in 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]
