Not trying to be smart or pedantic: modern routers are built out of lots of
"ASICs". I imagine the forwarding element design is the differentiator:

1. Fixed pipeline: EARL family
2. Progammable pipeline: UADP family
3. Run-to-completion: "Silicon One" family

Not an exhaustive list, lots of other examples etc...
