The Intel i7-4930K has six cores rather the standard four. The additional two cores improve multi-core throughput by 50% but leave single and dual-core speeds unchanged. Comparing the 4930K to the 3930K, its predecessor, shows that little has changed in terms of performance. At peak performance when both processors are overclocked the 4930K leads by around 7%. As well superb multi-core performance, both processors also have very strong single and dual core performance. The main downside to the 4930K is the fact that it still runs on the same FCLGA2011 platform as its predecessor, as a result purchasing it would effectively mean buying into a technology that is over three years old. In most cases, it would probably make sense to wait for a Haswell based hexacore. [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]
