AMD had an interesting demonstration at CES this week where they compared one of the new Fusion based E-series APU netbook against an Intel dual-core N550 netbook when viewed through a thermal camera.  The results were intriguing – both machines were playing back 1080p video on YouTube and while both were stutter free experiences, the heat produced by the Atom machine was definitely higher.  

This is honestly the first time we’ve been able to say this about AMD but it looks like they have the most efficient mobile processor around, for now.  Intel hasn’t talked about CULV Sandy Bridge parts yet but that might be where Intel has to go to really compete with the well engineered APU.
