    Hey, I'm not too knowledgable on Intel procssors, and I was wondering which is more powerful, Celeron M or Pentium M?? And how much is the difference?
    How does a 1.6Ghz Celeron M compare to a 1.73Ghz Pentium M?? :confused:
    Any comments/answers will be very much appreiciated! :)

    Pentium M is faster, I think the Celeron is their budget proccessor but I could be wrong, I dont know much about this myself.

    Celeron M is intel's budget mobile processor, its a crippled pentium M. It has less L2 cache (1mb instead of 2mb), a slower front side bus (400 instead of 533) and it doesnt have the enhanced speedstep technology.

    That makes it slightly slower and less power efficient.

    it not really an intentional crippling like what apple will do to there non pro computers.

    It more one of the failed Pentium M. Like something wrong in one of the catches so they disable bad part so it can not be used. And then they ton down the rest of the specs. Noramlly it a chip where there was a failure in one of the sections that can easily be disabled so it does not effect the chip negitily and the chips them selves are just fine.

    It more of a way for them to help keep cost down because instead of having to completely thow the chip way they just removed the damage area and sell the chip as a lower modil. Beside that the chip is 100% fine and no negitive damage since the specs are toned town to bring everything with in the stress tolercents with in specs and so the chip will still have it a 10 year life span before failure

    Yeah thats how they normally proceed. However, when demand for a budget chip is greater then the number of higher end processor with somekind of defectuosity that can be recycled , they will voluntarily cripple perfectly good processors to keep up with the demand.
    A good exemple that comes to my mind would be the "applebred" core AMD duron (lower end chip) that could be modded into an athlon xp (higher end chip) by retracing a cut made at the factory on some bridge. If you were lucky, that would restore the disabled l2 cache.

    Anyways we're getting a bit out of hand here and I thought it would simply be easier to say they're crippled then to explain the whole process like you just did. (dont think I could have done it better, nice job)

    fig tree
    celerons tend to be good overclockers (ever since the original, cacheless 300mhz one) because they start out as higher-clocked pentiums with a defect in the cache, and can clock up just fine. of course, i doubt this would work in a laptop.
