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 i5-3317U is a dual core, four thread, 3rd generation Ivy Bridge netbook and laptop processor. It launched in Q2 2012, and has since been succeeded by the i5-4200U which is a 4th generation Haswell (2013) processor. Comparing the 4200U and 3317U shows that, for 20% more money, the i5-4200U has a 10% faster effective speed and a 12% lower TDP. This is due to the newer and improved Haswell architecture. The TDP of 17 Watts should yield over 5 hours of battery life for average use. Like most mobile processors, the effective speed of 51.1 is poor, however, it's okay for handling the majority of day to day processing activities. The i5-3317U also has onboard HD Graphics 4000 which is sufficient for typical desktop use. [Nov '14 CPUPro]
