Essentially, what could the Sup720 handle if every packet hit the CPU? Does the architectural difference between the Sup720 and 7200/7500 at least somewhat mitigate CPU impact with CAR/policing?
So.. You should look into RSP720 and not SUP720 if you're buying new (more CPU, same list price).
I don't have any numbers on CPU forwarding performance on the RSP/SUP720, but basically you'd be very disappointed, it'd be in the few 100kpps range, whereas worst case performance with CFC only is around 15Mpps. Don't enable features that use the process switching path.
If you just want to move packets, RSP720+67xx series line cards will do just fine, plenty of grunt even without DFC.
