The FX-8370E is an energy efficient Vishera eight core desktop processor based on AMD’s Piledriver architecture. It was launched in September 2014 and is the energy efficient version of the FX-8370 boasting a lower TDP of 95 Watts versus 125 Watts on the FX-8370. Comparing the 8370E and 8370 shows that the lower TDP comes at a cost: the 8370E scores a relatively lacklustre effective speed of 73 compared to the non-E version which scores 83. The lower score is consistent with the relative clock speeds: 3.3 GHz on the 8370E versus 4.0 GHz on the 8370. Priced the same as the 8370, there is a direct choice between being green or speedy. Or, if you don’t really need the above average multi-threaded performance that the 8370E offers, then you may be better off with the superb single-threaded performance from any number of Intel’s offerings. [Dec '14 CPUPro]

The Intel Core i7-4790K, codenamed Devil's Canyon, is an upgraded 4770K, Intel's current flagship i7. The 4790K features an improved thermal interface which enables it to dissipate heat more efficiently than the 4770K. Comparing the 4770K and 4790K shows that stock performance has improved by 13% which is consistent with the base clock jump from 3.5 GHz to 4.0 GHz. OC performance remains unchanged. Comparing the 4790K and 4790 shows that at stock clocks the 4790K is around 16% faster which considering the small price difference makes the 4790K a far better choice. Previously Intel targeted the unlocked K versions at overclockers but with Devil's Canyon they have included VT-d on the K chip and this time it's squarely aimed at both power users and overclockers alike. Until the release of Broadwell in six months, the 4790K is the high end CPU of choice. [Jul '14 CPUPro]
