AMD probably doesn't think that people following the news will have much interest in anything but the A-Series desktop line of accelerated processors, and the Z-60 tablet platform, at least for a while.
With that in mind, we aren't too shocked to see next to zero mention of the APUs designed for business-centric systems.
Nevertheless, even if AMD hasn't actually announced them yet, their existence is known thanks to Lenovo's ThinkCentre M78 small desktop PC and HP's Compaq Pro 6305 PC.
