The Intel Core i7-920 is five and a half years old which puts it at an enormous disadvantage to more modern processors. The 920 sports four cores and eight threads which is the same basic configuration that Intel still uses in the majority of their i7s. Comparing the 920 to the 4770K, its modern day equivalent, shows that 920 lags by 63% at stock speeds and by 44% when both processors are overclocked. Overclocking improves the 920 by 30% vs just 17% for the 4770K. Aside from approximately 50% more calculation throughput the 4770K offers lower power consumption, compatibility with Intel's latest FCLGA1150 platform, on-board graphics and newer CPU instructions. Owners of the 920 should probably consider upgrading not only to improve system response times but also to take advantage of the newer platform. [Mar '14CPUPro]
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.
