    I was looking at a laptop earlier and saw that the CPU choice was a bit different to others I had looked at.

    It's starts with the 2ghz T5750 then jumps to the 2.1ghz T8100, where as most others have gone to the 2.2ghz T7500.

    The reviews I have read have said the T8100 is worth the £60 upgrade, but I don't understand how 100mhz clock speed and 133mhz FSB increase provides that much difference? Especially when the memory used runs at 667mhz (the same FSB as the T5750). Could someone explain this to me? It doesn't seem to be as straight forward as other laptops due to what looks like a change in architechture for the cpu?

    Pretty confused so explanations are warmly anticipated.

    p.s. I did some googeling and couldn't find any reviews that pitched it against the T5750.

    Edit:

    Found an answer by searching for T7500 vs T8100 - the latter is the new penryn based unit, I think I'll stump up the extra cash for that cpu, by the time i come to get it in august it might be standard anyway.

    The Penryn based part has the same archetecture tweaks as the desktop part IIRC.
    I must be reading different specs because from the specs I'm looking at, the 8100 is 2.1GHz, 3MB L2 cache, 800MHZ FSB being the main specs. The 7500 is 2.2GHz, 4MB L2, and 800MHz FSB.

    You've got that right, it's got less cache and clocked slightly slower, but out performs it and uses marginally less power.
