The Core i7-4790 is the third upgrade to Intel's flagship quad core hyper-threaded CPU. This version, like its predecessor the i7-4771, gets a 100 MHz bump in stock frequency and additionally the i7-4790 also gets a 100 MHz turbo frequency bump. These improvements (~4%) are marginal and practically impossible to discern in day to day use. Looking at a benchmark comparison between the 4771 and 4790 verifies that there is little difference between the two CPUs. Although the i7-4790 isn't much of a step forward, it's still one of the best (locked) mainstream processors on the market. AMD hasn't been able to compete with Intel on single threaded performance for several years, consequently Intel have no need to push the envelope. Overclockers should wait for the 4790K which is rumoured to be released shortly. [May '14 CPUPro]

MORE DETAILS

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]
