The Intel 5930K is Intel's new middle tier Haswell-E prosumer CPU. This model has base/turbo clocks of 3.5/3.7 GHz and sports 6 physical cores with 12 hyperthreads. The 5930K offers enormous processing throughput but like its Haswell-E siblings it lacks in single and dual-core speed. Comparing the 5930K and 4790K shows that the 4790K offers nearly 20% more single and dual core throughput and is priced nearly 40% lower than the 5930K. The 5930K does win hands down on multi-core workloads but these are not generally relevant to consumers. Finally since the Haswell-E architecture is coupled with the X99 chipset it requires far more expensive DDR4 RAM with offers little upside over DDR3. [Sep '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]
