this is the lspci output from an arista ethernet switch, the control-plane processor is basically an amd laptop sourced from components on the imbedded roadmap. while not an apples to apples comparision device wise (trio is a lot more functional than the broadcom) it's a passable example of embedded x86 control plane in a 1u l3 ethernet switch.
