Which advantages are you thinking of?

That's not possible though. If you look at the system architecture, the two are quite different and that has a major impact on the GPU.

Battery power of course. I do agree that it's very system dependent.

Sandy Bridge was never really meant for 17W. Ivy Bridge actually makes sense there, and Haswell will be an excellent fit.
Also, what would you consider the 17W Llano results?
