Pretty much, yes.  Of course with CRS-1 and IOS-XR you get an actual 
chassis-based router with router features such as fully-featured MPLS 
and enough memory to carry multiple full routing tables with room for 
growth and 'continue' in route-maps* and linecards and upgradability and 
a forklift to install it.

I'm glad that Foundry tends to publish Mpps numbers for 64 byte frames 
and not do the "double all numbers and call it full-duplex" marketing 
stunt that Cisco is so often guilty of.
