An atom should easily be able to forward some high fraction of a gig
between two pci-e 1x connected interfaces certainly in the soho context
such a box can do ipsec at farily reasonable rates as well.

Regarding equivalence to a PIII an atom is a scalar rather than super
scalar device. it is slower clock for clock than a pIII but there are
also multicore variants and of course they run faster at loewr poper
consumption rates than the equivalent PIII  derived embedded processor
such as the intel a800
