The third gen Ivy Bridge Core i7-3770K can't really be described as a consumer orientated processor. With 8 threads and four cores its capabilities are better aligned to server use. For price insensitive consumers that want the best of the best, this is currently one of the fastest processors available. The PassMark Single Thread score of 2080 points puts the 3770K right at the top of the pack in terms of raw processing power and real world performance. The GeekBench and PassMark scores of 17210 and 9653 are within 20% or so of the best we have ever seen. Despite the near record breaking processing throughputs the 3770K is only rated at 77 TDP, which is very low by historical standards. For typical consumer use there are better value propositions out there. [May '13 CPUPro]

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]
