QorIQ is pretty cool, but for whatever reason there's massive hype about ARM servers and zero about PowerPC. Perhaps this is evidence of an information cascade.

If Facebook is already getting custom Intel and AMD motherboards, ARM motherboards should be no problem. (Note that a major undercurrent of Facebook's announcement is that "custom" is actually cheaper than "commodity" at "Web scale".) ARM server chips (Armada XP and Calxeda) don't have GPUs.
