    Difference between laptop cpu's

    Am really tempted to buy one of the cheap Dell laptops which are currently on offer atm.

    I am curious as to whether there are any real performance differences between a Celeron 370 (1.5ghz 1mb L2 cache) and a Pentium M745a (1.8ghz 2mb l2 cache)

    is it worth paying an extra £60 for the pentium m745a or not?

    thanks

    Have a laptop myself with the 1.8 pentium m installed and although I have'nt used the Celeron 1.5 I can say that the Pentium m is really quick and if its only £60 more i'd say get it.

    I don't think the Celeron based laptops support the whole wireless thing (Centrino?)

    nope, also you should see improved battery life with the Pentium M.

    The only diff (so i have read on the intel site) is that the celeron m has 1 MB of cache rather
    than 2 MB and doesnt have speed step or whatever its called.

    The Celeron D CPUs are fairly decent - on a par with the equivalent Sempron CPUs. Reasonable overclockers too. However I'm not clear on how the D core applies to mobile Celerons (if at all).

    The celeron M near enough performs the same as an equivalent Pentium M. A 1.6 GHz celeron M will generally out perform a Pentium M at 1.4 GHz.
    Some people dont really know or understand the difference between the early celerons
    and the latest ones.

    You have to consider the performance of the HDD in the laptops and the graphics chipset.
    The difference between a 4200 rpm HDD and a 7200 rpm would be more important.

    CPU wise it only matters if you are bothered about battery life.

    Centrino is just more marketing from Intel.

    although I'd also ask.....does one have more system ram that the other? If so, get the higher system ram....

    The Celeron being compared is a Celeron-M, folks, not a Celeron-D.

    I'm not certain, but I don't think there are any differences between the P-M and the C-M except for the cache - I'm not aware of any power management differences (not that I've ever used a Celeron-M AFAIK).

    Celeron M = Half the cache and no "EIST" so no dynamic multiplier or voltage changes, which is why it would be somewhat worse than the Pentium M for battery life - the extra cache helps here too but TBH it depends on how the laptop is set up (software is needed to control EIST, it's not automatic) and how it is going to be used. Bottom line is that the money is probably better spent on extra memory, a bigger HDD or an extra battery

    Ah - I didn't realise the Celeron missed the EIST circuitry.

    Actually, it's more than just wireless...

    Integrated Wireless LAN Capability
    Outstanding Mobile Performance
    Enables Great Battery Life
    A Variety of Laptop Designs


    Straight from the Intel website. Officially there are no Celeron Centrino PCs, only Pentiums. This is what I was trying to highlight.

    I agree it's marketing blurb, but then again so are a lot of the reasons why people buy one PC or component over another.

    Other marketing successes with no real benefit include: Dual channel RAM, ATA 133 hard drives, SATA II 300 (indeed SATA I 150 as well), etc, etc.

    Anyway, this is getting a bit off topic.
