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 Intel Core i5-4690K is the latest incremental upgrade to Intel's unlocked mid-range quad core family of processors. The 4690K replaces the 4670K. Comparing the 4690K and 4670K shows that little has changed. The two chips share identical architecture; in fact the only difference between them is a 100 MHz bump to both the base and turbo clocks. The 100 MHz bump translates to an insignificant 2.9% performance increase. In terms of outright performance the 4690K has an effective speed of 103 which thanks to its superb single and dual core performance, is 12% stronger than the average of the group leaders. Overall the 4690K brings nothing new to the table so owners of previous flagship i5's will gain little by upgrading but as a new purchase the 4690K is a strong contender for both power users and high end gamers. [Jul '14 CPUPro]
