You can argue it both ways, one the one hand windows benefits from the last 15 years of x86 optimization. On the other hand arm is benefiting from a lifetime of embedded optimization. Intel has only relatively recently shifted their focus to low wattage parts, and this demonstration on atom is not on their latest process. What this benchmark shows is that the speculation about x86 being inherently inferior to ARM for low wattage is just that, speculation. x86 and Arm are very much in the same ballpark and we can expect the competition to really heat up in the coming years.
