Your point about battery life is taken for older AMD CPUs, however with the new "cool and quiet" setup, the cpu actually loafs along at less than 1/2 normal speed, picking up speed as load increases... it's not the CPU that's hurting batter life in AMD systems, it's usually the chipset. But yes, intel based systems generally do give you a slightly longer per-charge playtime.
