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]

In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two generations. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. Where the AMD FX makes up is on multi-core performance, with a score of 9156 vs 6745, the AMD leads the Intel 2500K by 36% making it the far more capable multi-threaded server orientated performer. The 8350 is also cheaper but significantly more power hungry which counts strongly against it as a server proposition. The FX-8350 could be a good fit for specific server use cases but for general consumer use, which is single and dual core intensive, Intel's two year old i5-2500K delivers better performance. [May '13 CPUPro]
