I'd say Intel. They're way ahead of AMD, they're coming out with 45nm chips soon, and AMD hasn't even touched 65nm yet. Not only this but Core 2 Quad is already out, as well as the Xeon versions. Intel is just way ahead of AMD so far. To me it seems like AMD is just coming up with a bunch of stupid ideas as of late. 4x4 won't go anywhere, Torenza is stupid, and the acquisition of ATI has yet to prove useful. I think AMD is just way in over their heads this time around.
