I was always wondering why are Intel Sandy Bridge Extreme series CPU named as 3000 series and not 2000 series. To me it's logical that if the 1st generation Core i7 Extreme are named as 9xx and 2nd generation Core i3, i5 and i7 are 2000 series then Core i7 Extreme Edition should also be named as 2000 series. Even the mobile 2nd generation Core i7 Extreme Edition CPUs are 2000 series. Also all other desktop oriented Core i7 Extreme Edition series names are pushed into another series name. Why and is there a reason why did they do it starting from Sandy Bridge?
