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]

The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]
