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 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]
