I don't track the Atom family and not sure if C2000 is the new out-of-order version, but until that is available - this is no comparison by a long shot. Also 5w on the cpu package could easily be made up for in a superior motherboard and chassis design. Think about how much power interconnects takes, PCIe and everything else..
