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]

The FX 6-Core, like most CPUs from AMD, delivers reasonably good server orientated multi threaded performance and consequently good processing thoughput at a reasonable price tag. Where the FX 6-Core lacks is in the area of single core performance which although not normally a major problem for server workloads, is always very relevant to desktop users. The overall performance of the FX 6-Core is comparable to Intel's five years younger Core i7-950. There are server orientated use cases where the FX 6-Core will excel thanks to its excellent overall throughput and in those instances the FX 6-Core represents good value for money. But typical desktop users will find far better value elsewhere[Sep '13 CPUPro]
