After brief teases from HP and others, AMD today confirmed full details of its 2010 notebook chips. The mainstream processors are now known to be much more power efficient than both previous AMD chips and Intel's quad-core hardware. The four-core 2GHz Phenom II N930 and the 1.6GHz P920 use just 35W and 25W of power, rendering either of them miserly enough to sit in thin-and-light notebooks.
