The 3930K has an outstanding multi-core performance profile, almost as good as you can buy at any budget, which considering its relatively reasonable price tag really make it stand out from the crowd. The reason for the extraordinary multi-core benchmark scores is down to the 3930K's six cores. Having six cores effectively results in a 50% lead over quad core cpus and a 200% percent lead over dual core cpu's. Typical desktop users rarely use more than two cores simultaneously thus rendering the additional four cores largely redundant for consumer use. In terms of regular use this CPU will offer virtually no better real world performance than the leaders in my Desktop CPU Group Test. For server orientated workloads the 3930K offers both outstanding performance and superb value for money. [Jun '13 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]
