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 i5-7600K targets high end gamers, it sits just behind the flagship i7-7700K in Intel’s Kaby Lake lineup. The 7600K will likely be the most popular gaming CPU of 2017 (some competition from AMD’s upcoming Zen/Ryzen CPUs, would be very welcome). Comparing the 7600K and 6600K shows that the two processors are very closely matched and comparing the 7600K vs the hyper-threaded 7700K highlights the relative strength of the 7700K for workstation performance. There are no significant architectural differences between Kaby Lake and Skylake so, when fully overclocked, the two generations should perform similarly but Kaby Lake offers faster base clocks, improved speed shift technology which helps CPU responsiveness, and better integrated graphics[Jan '17 CPUPro]
