The APU concept has a few interesting points but certainly also a few major 
problems (when comparing it to a cpu + stand alone gpu setup):

 * Memory bandwidth to all those FPUs
 * Power (CPUs in servers today max out around 120W with GPUs at >250W)

Either way we're in for an interesting future (as usual) :-)
