The Intel Core i7-4790K, codenamed Devil's Canyon, is an upgraded 4770K, Intel's current flagship i7. The 4790K features an improved thermal interface which enables it to dissipate heat more efficiently than the 4770K. Comparing the 4770K and 4790K shows that stock performance has improved by 13% which is consistent with the base clock jump from 3.5 GHz to 4.0 GHz. OC performance remains unchanged. Comparing the 4790K and 4790 shows that at stock clocks the 4790K is around 16% faster which considering the small price difference makes the 4790K a far better choice. Previously Intel targeted the unlocked K versions at overclockers but with Devil's Canyon they have included VT-d on the K chip and this time it's squarely aimed at both power users and overclockers alike. Until the release of Broadwell in six months, the 4790K is the high end CPU of choice. [Jul '14 CPUPro]

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]
