    I just found this info on the upcoming Core 2 mobile chips on Wikipedia. The Core 2 Extreme X9500 has a TDP of 44 Watt, indicating that it would be perfectly suitable for the 24" iMac. That machine would be much faster than a Mac Pro in single-threaded tasks ... :cool:

    ... however no release date for the chip is indicated :(

    those things will be stupid expensive and won't be worth it

    You think they would cost more than the previous generation $851 Core 2 Extreme X9100 ? Have they ever made a mobile chip that costs more than $1000 ? If it's indeed that expensive, I agree it's probably not worth it.

    To me, even the old core 2 extremes at $800 are not worth it. I personally believe it's kind of stupid to go top-end hardware on a machine that is not a desktop, but that's just me.

    That's more incentive for Apple not to go quad on the iMac. Mid-2007 2.8GHz Core 2 Extreme iMac had X7900 @ $851 (although cheaper in bulk for Apple) so I can see them going for it. You want more cores? Go for the Mac Pro they'll say.

    :eek: What the… :eek:

    There's quite a few others I haven't seen before…

    T9950: Dual-core, 3.19 GHz, 35 W ($851)

    X9300: Dual-core, 3.33 GHz, 44 W ($851)
    X9500: Dual-core, 3.72 GHz, 44 W ($1038)

    QX9200: Quad-core, 2.40 GHz, 45 W ($851)
    QX9500: Quad-core, 2.93 GHz, 45 W ($1038)

    Prices in parentheses are my guesses.

    These to me raise other questions (assuming they are real). Why would Intel release a bunch of quad-core CPUs soon when Clarksfield is likely to come a quarter later? Is it because Clarksfield is delayed?

    The dual-core 35/44 W CPUs also are interesting since Arrandale will supposedly top out at 35 W (including iGPU, which means ≈25 W CPU). I wonder if Intel is planning to keep a set of high-clocked dual-cores in 2010, and those happen to be Penryns instead of Nehalems (not likely IMO).

    QX9300 mobile quad-core is $1038.

    For the average user isn't there a point where this just becomes overkill?
    It seems once you reach a certain point the rest is really unused potential by average and most advanced users....
    Just a thought;)

    That sounds ridiculous. Next step will be quad-core and after that 32nm processors. 3.72GHz dual core is slower than 2.53GHz quad core and it's cheaper so....

    Plus not even the desktop dual-cores are 3.72 GHz…

    I would love a 3gHz quad-core MBP. I'd sell my current 2.8 for one.

    The E8700 comes close. Not that you can't overclock it. Intel is cherry picking these processors though.

    Not that you need this kind of clock speed unless you happen to think you're CPU bound in gaming.

    How does this work in practice? Do they somehow test each processor right after fabrication as to how high it can go in clock speed? Why is there so much variation from one processor to the other? Does it have to do with leakage currents? I could imagine that those currents depend very sensitively on how close things get to each other on the chip and there may be some fluctuations in the distances during the fabrication process - just a wild guess, but I'd love to hear an explanation from someone who is knowledgeable.

    Well, another good use for high clock speeds is for simulations that cannot easily be made parallel - we do have problems like that at work.

    People said the same thing years ago about 3.0 GHz and look what we have in the iMac now.
