    celeron m

    is the celeron m a cut down version of the pentium m and is it any good?
    Im not getting a laptop but someone i know is and as im not i havent ever
    bothered to keep up with such things.

    This person is only really going to be using it for internet office and the odd
    game i suppose. I suggested getting a mobile one instead of a desktop
    replacement.

    Also what about the old mobile graphics stuff. I see many of these mobile ones
    with Ati X300 / or 9700 pro or the good old intel Intel 915GM bollocks and sometimes a 6200 go with that dodgy hyper turbo ram thing. What order would you put them in and a % of how good the next one is over the one below roughly?

    yea, also interested in this, my brother wants a budget laptop.

    How does the Celeron M compare to the Sempron mobile ?

    They perform pretty well and they should be faster than most Semprons, especially if you stay with the 1MB 90nm chips. Go for 350 and above for normal Celeron M, or 380 and above for Ultra Low Voltage models and they should be very fast.

    pentium-m isn't a massively cache-dependant design (unlike pentium 4, which falls hard with less than a few meg of cache), so the celerons are pretty good all things considered

    I have read that the cel m doesnt have hyper threading or speed step. Thats not
    such a big deal, right?

    Do all the 130 nm chips all come with 512 KB? prob is they dont really mention much what
    exact chip they come with... or maybe they do. Do the 3xx number change depending
    on if 90 nm or 130 nm?

    Do the cel m's sometimes use ddr2 or always 200 MHz DDR400?

    The "M" series is about twice as fast clock for clock as the normal P4, and much more energy efficient. If you don't run multiple CPU intensive applications you will not miss HT.

    There are two generations of Celeron and Pentium M

    The first chips (Banias core) were 0.13u and had 512K L2 cache for the Celerons and 1MB L2 cache for the Pentiums.

    The second generation chips (Dothan core) are 0.9u and have 1MB L2 cache for the Celerons and 2MB for the Pentiums. There are also some chips with a 400MHz FSB and some with a 533MHz FSB. Clock for clock these cores are faster so at least in theory a 0.9u 1MB chip (Dothan Celeron) would be faster than a 0.13u 1MB chip (Banias Pentium)

    For laptop use though - and I'm talking about someone REALLY using it as a laptop (i.e. on the battery) I'd recommend the extra cost of the Pentium M over the Celeron M as the enhanced speed step (EIST) is disabled on both the 0.13u (Banias) and 0.9u (Dothan) Celerons. So an older (Banias) Pentium M would be better for battery life (and heat) that a newer (Dothan) Celeron M (if the laptop is set up right the Pentium M can be made to throttle down to 600MHz / 0.7V when the extra CPU power isn't needed). If anyone's thinking of using one as a desktop then go for the 0.9u chip because it will overclock better.

    For what it's worth I have a 1.3GHz 1MB cache (Banias) Pentium M in my HTPC and a 1.3GHz 1MB cache (Dothan) Celeron M in my main rig at the moment. The Banias does 1.8GHz @ stock volts (1.36V IIRC) whereas the Dothan does nearly 2.2GHz at a lower (1.23V) stock voltage.

    Edit: Oh and Kumagoro, it's the mobo / chipset that dictates the type of RAM used in the world of Intel (and AMD before the A64)
