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 '14 CPUPro]

The AMD FX-8320 has the same architecture and specs as the FX-8350, the only difference being the base/turbo clocks of 3.5/4.0 GHz for the 8320 vs 4.0/4.2 GHz for the 8350. Comparing the two models shows that the 8320 lags the 8350 at stock speeds by around 10% but broadly matches it when both processors are overclocked. This combined with the 8320's considerably lower price tag makes the 8320 the better value proposition. In terms of outright performance, as with all AMD CPUs, the FX series have very strong multi-core performance but lag Intel considerably in terms of single and dual-core throughput. [Mar '14 CPUPro]
