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]

MORE DETAILS

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 put 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 also very reasonable by historical standards. For typical consumer use there are better value propositions out there. [May '13 CPUPro]
