Over on the AT forum thread about AMD results, a user Vattila put together a chart of the various margins:

(AFAIK only possible because AMD change the way they reports on divisions).
Now that the Operating Margins are as the report things and I'm sure they have interest to distribute costs so as to pay less tax, but the new division
Gaming has pretty poor margins. Theory is that they've lumped GPUs and consoles in there (think consoles used to be under Embedded but that's now mostly Xilinx.
Still doesn't tell us the whole story as GPU prices have come down a lot and consoles are still in there. But Data Centre and Client should be where most of the CPUs are. And while AMD sell few cheap CPUs, Data Centre is only 32%. Hard to tell, but it is possible that Intel have been underbidding AMD as their server chips are rather poor now.
