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 Core i7-4770K is Intel's fourth generation (codename Haswell) flagship processor in the hugely successful Core range. It's not surprising that the 4770K sets a new Real World Performance index record, besting its predecessor by just over 9%. The 4770K also tops out in the remainder of our benchmarks setting new highs of 10020 and 2164 in the PassMark and PassMark Single Thread tests which equates to roughly an 8% overall performance increase over the 3770K. With a TDP of 84 watts, power consumption has increased slightly over the 3770K. The new Core i7-4770K demonstrates around an 8% performance increase over its predecessor the 3770K but it costs 12% more. As a result, at least until prices drop, this processor represents marginally worse value for money than the 3770K. [Jun '13 CPUPro]
