Unfortunately as we’ve seen time and time again with AMD, while their Graphics division can consistently turn a small profit, at only 1/3rd the revenue of their Computing Solutions division it’s not nearly large enough to offset the losses AMD has run there.
In Q3 of 2011 Llano was the biggest factor in AMD turning a profit, but a year later those chips have been superseded by AMD’s new Trinity APU.
