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 Core i5-4690 is Intel's latest and greatest locked Core-i5. This CPU will suit serious gamers that don't plan on overclocking. The 4690 replaces the 4670 and shares exactly the same specs aside from base and turbo clock bumps of 100 MHz. The 100 MHz clock bump results in barely noticeable real world performance improvements and, if anything, makes the older 4670 more attractive as suppliers reduce prices to try to clear stocks. For regular desktop use such as email, surfing, and listening to music, this CPU is overkill and there is far better value amongst lower powered and significantly cheaper CPUs but for gamers and moderate power users the 4690 is a good locked option. [Jun '14 CPUPro]
