Launched for pre-order on the side-lines of Computex 2014, Intel's flagship quad-core processors for the LGA1150 platform, codenamed "Devil's Canyon," are now shipping from retailers, and can be bought off the shelf on ground stores. Based on the 22 nm "Haswell Refresh" silicon, these chips are designed for overclocking, featuring higher voltage limits, packages designed to tolerate higher voltage, stronger electricals, and an improved thermal interface material between the die and IHS.

The series includes the Core i5-4690K, and the Core i7-4790K. The i5-4690K is clocked at 3.50 GHz, with Turbo Boost frequencies of 3.90 GHz, and features 6 MB of L3 cache. The i7-4790K, on the other hand, is the first Intel Core processor to ship with out of the box clock speed of 4.00 GHz, and Turbo Boost speeds of 4.40 GHz. It features 8 MB of L3 cache, and HyperThreading, which enables eight logical CPUs for the OS to deal with. The i5-4690K is priced at US $250, and the i7-4790K at $350.
