A Christmas present for Neelycam - detailed Z2760 Atom power

Very illuminating article at Anandtech measuring Tegra 3 versus Atom Z2760 power draw in detail at the component level. Intel has a test system that measures power directly from the power delivery circuits for CPU and GPU (although Anand says the GPU rail may be powering other circuits, but only because the GPU power draw seems so high. Maybe the power efficiency explains why Apple likes PowerVR graphics so much too though.) Granted it's Tegra 3 which is made with TSMC's 40nm and not the newest ARM architecture at this point, but it bodes very well for the Intel's future in medium power draw mobile devices (tablets), then when Atom goes OoO and 22nm with Silvermont then 14nm all bets are off for the smartphone market too.
