The Intel 5960X sports eight cores and sixteen threads. That's two more cores than we have ever seen on a consumer processor before and as such this $1,000 processor offers record breaking multi-threaded CPU horsepower. Unfortunately the 5960X is clocked at just 3 GHz base and 3.5 GHz turbo which, for single and dual-core workloads, renders it around 15% slower than a $69 G3258 on stock clocks! The 5960X is only compatible with Intel's new X99 chipset which requires new DDR4 RAM and is currently far more expensive, with little consumer benefit, than DDR3. All in all the i7-5960X processor is largely irrelevant for consumers as it's far far too expensive. [Sep '14 CPUPro]

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]
