The Ageia hardware isnt anything unique... there are dozens of specialist floating point math chips that do this sort of stuff. The only thing Ageia has really got is their SDK and tie in with "games". Not much there for AMD really. Better to just go any buy a REAL math team, and pawn the SuperPi benchmarks by having some true vector math co-pro built into their CPUs.
Ageia is NOT NEEDED to get AMD out of the doldrums. Sounds like a bit of diversionary tactic to me.
AMD board should fall on their swords.
