for clarity, I think a 'normal':
 o 7200 these days ships with a 1ghz cpu
 o Cisco CRS ~2.13ghz Intel
 o Juniper M/T/MX ~2ghz Intel
 o Cisco 12000/XR (prp2 single-core, 3 dual-core) 1.3GHz PPC

None of these is an order of magnitude smaller than a desktop-cpu.
Even a 7500 with a 600mhzRISC is not an order of magnitude. (by the
mhz/ghz numbers at least, speedups in math done in assembly aside)
