The Guru of 3D published a review on the Core i7 4790K 5.0 GHz - - A Silicon Lottery
A quote from the article:
You know back in June Intel released Devils Canyon processors, the newly revised Haswell based quad -core processor was to be the hottest 'thang' for overclockers. Unfortunately the results where a bit of a mixed bag, actually the 4770K in a lot of circumstances could be tweaked higher than the 4790K which maxes out mostly in the 4600~4700 MHz range when overclocked. Back in June with Devils Canyon processor release I seriously had a goal to reach the 5 GHz marker with that processor, but whatever I tried, the sample that we retrieved from Intel absolutely maxed out in the 4700~4800 MHz range. So in the back of my head, that always was a bit of an annoyance (with an otherwise lovely product).Core i7 4790K 5.0 GHz - Review - A Silicon Lottery @ Guru3D
A little while ago in our forums somebody mentioned a website based in the 'Silicon Lottery'. The website is selling binned processors, guaranteed to work at a certain clock frequency. Though the idea is nothing new as there are parties out there that purchase a 100 processors and then make a selection, ending up with the best overclockers. So with that 5 GHz marker nagging me, I figured what the hell, Silicon lottery is offering a wide variety of 4790K processors which are binned, what is binning ?
