    You would first think, why of course the T5250 as its only 1.5GHz...

    ...but different technology's.

    Which would yield a better battery life? Looking to pick up a used T7500 if I can find one for a good price.

    What about the T9300?

    Both processors are 35W, but the T7500 has a lower voltage at it's lowest speed than the T5250, but the T7500 has a much higher voltage than the T5250 when it ramps up.

    Besides this, the T7500 has an 800MHz fsb which is faster than the t5250's 667, so maybe that would be more power consuming from the very start.

    I'm not sure how much this would account for in terms of battery life, but I wouldn't buy that processor for the sole purpose of gaining more battery time.

    t7500 has a higher fsb and more cache, so i guess it could run hotter.
