    Comparing the fastest i7 to the i5 processors offered in the Sony Z12 new Z13 make the notebook:

    - run warmer?
    - make the fan turn on more?
    - use more battery power?

    Thanks

    yes
    yes
    yes

    albeit not too significantly over the i5 (it's still a 25w part like the i5 afterall)

    I second those answers by beaups, but not significantly, but then again the i5's are very capable chips in of themselves. I think a few have mentioned that the performance diff between a i5-540m and an i7-620m can only really be measured in benchmarks(unless you're using some program that can actually utilize all your processing power).

    the upgrade to the i7 is not really worthy it, its just a masturbatory move.

    and while there you get a lower battery life, since the TDP of the i7 is 35W and not the 25W of the i5.

    I agree that you should always vouch to get the best processor, if it is worth.

    Also the i5 has 35W TDP. It is a marginal difference concerning battery life due to the higher clocks. The i7-620M is about 10% faster than the i5-520M (Cinebench R10).

    i5 540M is the one to buy, imo

    The differences are minimal, both are fast.
    But for resale value, i7 is better. Also many buy the Z for the show, and for that reason an i7 is always impressive. And due to the extra MB of cache and high clock speed and turbo mode speed the i7 is a tiny bit faster.

    I've got the i7 version but thats only because the Z12Z was/is the pre-configured model over here with 8gb ram, the 4x64gb ssd array and fullhd screen. If they used an i5 for that model I still would have bought it just for the ram, ssd and screen. But it never hurts to have more performace :D

    The performance+ can only be measured by benchmarks. In normal usage you won't notice anything.
