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]

MORE DETAILS

The Intel Core i7-4770 features Intel's most recent (Haswell) architecture. As with each of the previous "Core i" generations Intel have managed to reduce power consumption and simultaneously increase processing throughput. The i7-4770 has a locked multiplier which makes overclocking it much harder than its unlocked i7-4770K sibling. Comparing the 4770 and 4770K shows that the 4770K yields 14% higher processing throughput when overclocked and also costs 14% more. The 4770K has 4 physical cores which allow it to process four streams of instructions in parallel. General desktop computing tasks such as checking email, watching videos and surfing the web rarely require more than two cores, so for the majority of users this processor is overpowered. If you plan to encode video or compile software then this is one of the fastest reasonably priced processors available. [Mar '14 CPUPro]
