At nearly five years of age the AMD Phenom II X4 965 has been included in the CPU group test primarily as a reference. This hugely successful CPU from AMD has been one of the most popular gaming PC's of all time. With superb Single threaded, and therefore real-world performance, the X4 was able to compete with Intel's first generation of Core chips in terms of raw processing power and it did so at a lower price point. Today of course the X4 processor has been far surpassed by Intel's third and fourth generation Core processors. [Feb '12 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]
