The primary differance is the NSE is it is only supported in the
7200VXR and incorporates the PXF processor for accelerated packet switching.

To get VXR performance you must use at least a NPE300 and you get a
MIX backplane, good for voice stuff. Also the VXR gives you increased
backplane bandwidth capabilities.
With the new NPE-1G you no longer have any bandwidth point limitations!
