Right, well you'd have to work through some damn big differences. There's a reason why Llano has 2X the ROPs of IVB. It's the system architecture.

So wouldn't you say that IVB is the better 17W solution?

Just like I'd say that a Cortex M0 (or whatever is used) is a far better solution for a hard drive controller than an Intel Atom?

It's possible.
