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 Ryzen 5 1400 is the entry-level chip from AMD's latest Ryzen 5 series which is aimed at the mainstream market. The 1400 is a budget quad core, 8 threaded CPU with base/boost clocks of 3.2/3.4 GHz. Like most the other non-X Ryzen CPUs the 1400 comes with a decent cooler included in the box (Wraith Stealth in this case). Modestly priced at $169 the 1400 is in direct competition with Intel's recent Kaby Lake dual core, four threaded i3-7350k which runs at a base clock of 4.2GHz. The 1400's 8 threads allow a near 40% lead in multi-core processing, but for single-core tasks the 7350K is 45% faster. The Ryzen 5 1500X commands a $20 premium and offers a 25% increase in effective speed over the 1400. Although the 1400 only has a base clock of 3.2 GHz it should more or less match the 1500X when overclocked. Provided it is overclocked, the 1400 joins the other non-X Ryzen models in offering the best bang for your buck. Users not keen on overclocking would probably do better to consider the 1500X at this price point. [Apr '17 CPUPro]
