Performance on newer Intel Atom boards?

Anyone have any experience working with ROS on the newer Intel Atom (Avoton/Rangeley) 8-core C2750/2758 boards like the SuperMicro A1SAi-2750F or A1SRi-2758F? Considering the CPU uses only 20W max, I’m curious what kind of routing performance it can achieve versus the CCR’s. Anyone played with these?

In my environment, a 2-core i5-4350U device is more powerful than CCR1009 as a VPN server (EoIP+IPsec, SSTP, OVPN).
