That barrier is now gone and NVIDIA says three vendors have products ready to roll that bring GPU-assisisted co-processing to market. The three are: .....
Separately but at the same event, AppliedMicro also announced that its ARM-based X-Gene “Server on a Chip” is now in a state of “readiness” and that “ … development kits [are] available immediately, and production [will be] silicon available imminently.”
Hmm, if that little collection of news doesn't get Intel quaking in their boots then I don't know what will.
Thing is there's not a lot Intel can do. They could buy (for example) AppliedMicro and shut it down, but that would merely encourage all the others. It would mean that an ARM based server is viable in Intel's eyes. Alternatively they could buy them and keep ARM going, but that would say the same thing too about ARM.
And where would their "x86 can do anything including low power" stance be then? Intel aren't going to change their development direction so far as I can see, but it is surely a risky strategy. What if ARM really does turn out to be a better server chip than Intel?
Thing is, if Intel did make ARMs they'd be the best in the world. Intel are very good at silicon manufacturing, and it would give them a tremendous advantage in the ARM market.
