Why doesn't it add up.
Why would AMD have absolutely accurate numbers?
Its ball park.
They are the ones responsible for manufacturing the chip so it's reasonable to think that they would have access to those numbers ...
I'd imagine they have supplied a lot more of the chips than have been used thus far.
Manufacturing isn't that kinfe edge for supply surely. If they have only supplied 30m chips then the shipments will be even lower.
Anyiow, it is all idle speculation. This certianly doesn't "confirm" anything. We should get at least some indication in the next few weeks though.
