    Is there any difference between C2D 6400 and 6500 CPUs? Which one is better?

    Frequency, the T6500 is clocked 5% faster (2.1GHz vs 2.0GHz)

    But you won't notice any difference during normal use.

    Does P8600 CPU produces less heat than T6500?

    Yes because it uses 10W less, it'll also make your battery last longer, because it's power consumption is lower.

    The TDP is 10 watt less. That does not mean it uses 10 watt less.

    In reality the difference in power consumption is much smaller.

    You also might consider whether you want to run an XP virtual machine under Win 7 in order to have full backwards compatibility and run XP apps. I don't know if the 6x00 series does, but you might check if that is important to you. Personally I would only buy a laptop that supports virtualization.

    the last C2D without Virtualisation was t5200 AFAIK, so it shouldn't be a problem here)

    I think my T5800 still doesn't support virtualization..I think.

    EDIT: Also, the ~10W TDP difference is easily compensated through undervolting, so sometimes it's a better choice to take a Txxxx and then undervolt it rather than a Pxxxx of the same specs (which would usually be priced higher)

    Although, the already-cool Pxxxx processors would be even cooler when undervolting. :D

    Don't a lot of Intel CPUs not support virtualization?

    I remember there was this huge scandal when MS first announced XP mode about how Intel was using VT for market segmentation purposes and how people with brand new C2Q's were suddenly discovering that XP mode didn't work on their machines.

    Thanks for the replies. I think C2Q 9*** series (9550/9650) support virtualization.

    Most of the T5xxx and T6xxx do not support VT.

    Will there be any improvement in speed for word processing and video creation applications with regard to 2.1 and 2.4 GHz CPUs? This is because in India, P8600 with 2.4 GHz is bit expensive. So I'm planning to get T6500 (2.1 with 3 GB RAM).

    It will depend on your usage. If you are a professional user executing heavy video creation jobs a P8600 will be about 20% faster during those jobs.

    For normal users it won't make much difference.

    Word processing = won't even see a difference.

    Video rendering = you'd see differences, but then again might just notice those differences between processors which have from 800Mhz onwards of clock speed discrepancy, considering processors w/ same FSB/ L2 cache. I think. :D
