    From a power consumption point of view, which stands to gobble less power, a Celeron M (540) or a low-end Core 2 Duo (T5270)? Supposing the Celeron has lesser processing power, does the latter have better power management?

    The Celeron has a TDP of 30W and the C2D has a TDP of 35W. So at full speed, the C2D will consume more power. However, the Celeron doesn't support SpeedStep so it can't downclock to conserve power. Overall, I think the Celeron will consume more power than the C2D.

    I'd go with the Core 2 Duo. The Celeron M has it's speedstep disabled so it'll always run at maximum speed and not reduce it's power usage.
    The Core 2 Duo can vary it's speed. At any rate I'd be willing to trade in some battery life to get a little more speed out of my laptop, even if it is for office work. I have a XPS M1210 configured with an T5500 and it gets about 4,5 to 5 hours of batterylife with medium usage.

    I've got a Celeron M 540 now and I'm going to try and upgrade mine to a Core 2 Duo T5250 when it arrives tomorrow hopefully. That's telling you to go for the Core 2 Duo! :p

    Personally I wouldn't ever really consider a Celeron. I've worked with Celeron machines on several occassions and whenever you start running a lot of apps they choke on it.

    The Celeron M doesn't...it's just a Core 2 Duo is a big leap in performance lol

    The lack of L2 cache does hurt the Celeron. It's fine for basic stuff, but its really worth it to go with a cheap Core 2 Duo if you can.

    I'd say it depends on wether or not it had Centrino Technology installed along side of it.

    If you've got a Celeron M Centrino, and a regular Core 2 duo, then Yeah, I'd say the Celeron M will use less power.

    But at the end of the day, Which Processor is going to be useful for how long?

    Most Core 2 Duo's you get today have Centrino Technology installed, and as one user said, It's got Dynamic Underclocking capability, Which allows it to automatically update it's clock speed for performance or battery life.

    Core 2 Duo All the way...

    (Plus, Core 2 Duo's, I -think- In general are 64 bit ready, which is always good considering I suspect within the next few years, the push to 64 bit will be huge)

    The Core 2 Duo will use less power in general usage.

    Dont forget about how hot your machine will run with the Celeron, hence the fan eating power up..

    Since I took out my Celeron 1.6ghz and installed my Core 2 Duo 1.73ghz T5300, my battery gained 50 minutes running time, thats at full performance Windows power setting and my fan barely kicks on. ;)

    Celerons cannot be part of the Centrino platform :(
