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 AMD FX-8320 has the same architecture and specs as the FX-8350, the only difference being the base/turbo clocks of 3.5/4.0 GHz for the 8320 vs 4.0/4.2 GHz for the 8350. Comparing the two models shows that the 8320 lags the 8350 at stock speeds by around 10% but broadly matches it when both processors are overclocked. This combined with the 8320's considerably lower price tag makes the 8320 the better value proposition. In terms of outright performance, as with all AMD CPUs, the FX series have very strong multi-core performance but lag Intel considerably in terms of single and dual-core throughput. [Mar '14 CPUPro]
