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 quad core and octa threaded Ryzen 1500X is a sub-$200 chip based on AMD's latest Zen architecture. It is released this month as part of the Ryzen 5 launch – a mid-market range specced out to challenge Intel's i5 series and yield considerably better multi-threaded performance at budget prices. Comparing the i5-7600K shows that the 7600K is 20% faster for single and quad core workloads but looses by 20% for multi-core workloads. The Ryzen 5 line-up also includes the 6 core 12 threaded 1600X. By comparison, the 1500X is 24% less expensive, comes with a Wraith Spire cooler and impressively yields very similar single and quad core performance, but multi-core performance lags 50% behind the 1600X. Both chips can be overclocked, but out the box, the base and boost clock speeds are 3.5GHz and 3.7GHz for the 1500X and 3.6GHz and 4.0GHz for the 1600X. The 1500X is a very reasonable CPU for the money, which thanks to AMD's recent IPC improvements, punches far above its weight for multi-threaded performance by Intel's standards. [Apr '17 CPUPro]
