I think its still a possibility, however remote now due to the response from intel.
From a tactical point of view if amd wanted to TOTALLY kill gsync (not that it needs much more, I would say this one is near death) and cuda then this would definately be the way to go..
and the person left out in the cold would be nvidia.
two ways of looking at it
a) I think a paycheck for amd for every intel cpu sold would be a god send to amd at the moment.
b) nooooooo, dont give away your crown jewels to your competitor... it removes the unique selling point of your APUS!
