    The t's are older than the p's offered by HP? T8300 VS P8600?

    yeah, HP is using the montevina microarchitecture (CPU designations "P"), AW is still on Santa Rosa (CPU designations "T" for Penryns).

    the AW motherboards don't support montevina... yet.
    I think the next lineup of AW laptops will be the ones montevina capable

    The performance difference between the two is not going to be noticeable, even in synthetic benchmarks. Montevina's just another platform.

    However, the Montevina's will offer a cooler processor by 10w.

    yeah right, just like when Santa rosa came out over nappa, they said the same thing, when Penreyns cameout they said the same thing, the lesser heat will be notable on lower freequency, but on full load, i dont think so.

    Heat may not be different, but battery life is increased, anandtech already showed this in their comparison of the 6860fx and the 7811fx

    The "T" ande "P" in the Montevina line up designate the watts. "T" is 35 and "P" is 25.

    And yes the x15 and x17 are not Montevina boards, they are Santa Rosa. Montevina is a new version of the Santa Rosa architecture.

    If you’re looking at either of those notebooks, then battery life is not a concern. On the other hand, the m15x already gets good battery life.

    P8600 will run cooler when at full load. The T8300 has good voltage tolerance, hence it undervolts well....
    Plus DDR3-1066 > DDR2-667 (25% performance increase)
    New notebooks w/new platform -> New BIOS -> New/Better GPUs

    I want to know how the heck everyone is coming up with "it will run cooler!" ....

    the process is still 45nm, the frequency isn't changing, the voltage isn't changing, the Cache isn't changing.... the only things that are changing is the FSB and the multiplier. they CLAIM a lower TDP for the chips, but I highly doubt there will be any significant difference in operating temps. manufacturers will just have cheaper, less effective cooling solutions. whopee.

    When you undervolt (say a T8300), you reduce the max power consumption (say by 10W), hence your Max Load temps drop down significantly ( probably by 15*C).

    The P-series already have the max power consumption reduced (by 10W), so it has a lower Max Load temp than the standard T8300 CPU ( say by 15*C ^).

    If you undervolt a P-series, you could further reduce the max power consumption, and hence reduce the load temps even more....

    It basically helps users to run intensive tasks, at not so-high temps.

    so this means.... you're robbing the CPU of power.

    greattttt.

    No, undervolting never increases/decreases performance in any way.... :p

    Check out the Undervolting Guide.
