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]


The FX-8370 is a top of the range black edition Vishera eight core processor based on AMD’s Piledriver architecture. It was launched in September 2014 and is both cheaper and faster than the FX-8350. The FX range offers high performance and this particular processor holds a world record for reaching an incredible 8.7 GHz when overclocked under lab conditions. For typical users however, the FX-8370 runs at 4.0/4.3 GHz (base/turbo) and typically hits 5.0 GHz when overclocked. Its effective speed is 83 which is currently only exceeded by AMD's 20% more expensive FX-9590 (scoring 85), making it relatively good value for money. Eight cores aren’t necessary for most applications, but things are changing and if you heavily rely on multi-threaded applications then the FX-8370 may be a good choice. [Dec '14 CPUPro]
