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 i5-4590 is a slightly upgraded version of the i5-4570. The two processors are identical apart from a 100 MHz increase in base and turbo frequencies. Needless to say the two processors have almost identical effective speeds which is a little disappointing as Intel has simply re-released a near identical product. From a value for money perspective the 4590 does fare reasonably well although it probably has more multi-core horsepower than most use cases demand. For the majority of users, at stock clocks, the G3258 provides comparable performance but with a few simple BIOS adjustments the G3258 can be clocked up to 4.3 GHz where, even at half the price, it destroys the i5-4570 in single and dual core workloads. [Sep '14 CPUPro]
