Last month Intel Introduced the Haswell Refresh processors. The newly introduced processors can easily be described as being the same 4th generation Core-processors we already knew, with the same price with a model number which is 20 points higher and a clock frequency which has been raised by 100 MHz.

Two processors however didn't receive an update: the Core i7 4770K and the i5 4670K, the uncocked models aimed at overclockers. Now Intel has also introduced the updated K-models under the code name Devil's Canyon. According to Intel these new models are even more interesting for overclockers. We test the new Core i7 4790K and the Core i5 4690K.
