    Is there such a thing as Turbo Boost with Qosmio Q850 i7 CPU?

    Alienware M15x claims to have this which basically auto-turbo when the CPU is heavily loaded. I'd like to know if this is an i7, CPU or motherboard, or driver dependent upgrade thing?

    If it's motherboard based boost, then I wont expect to see it on this Qosmio?

    All Core i7 processors numbered Core i7 720QM, 820QM, and 920XM have this feature, whether they be in an Alienware or a Toshiba. Long story short, any Core i7 notebook should have Turbo Boost, except for the Clevo D900F as this uses a desktop i7, and not a mobile version.

    From my understanding, Turbo Boost is increasing the CPU frequency when half of the CPU is in used?

    Jsteng, that is correct. if you're running apps that aren't really multicore aware or that pushes the processor to it's max thermal design the i7 could sleep up to 3 cores and speed up the remaining for faster processing. It can even increase the speed of all 4 cores for limited times depending on what kind of processing it is doing.

    It all relies on the hard set thermal barrier Intel coded. When it reaches that barrier no matter how much it's overclocked or how many cores, it will reduce itself back to keep within safe tolerances and power consumption.

    Pretty slick technology there.

    Now, the real question is how well does it work in real life situations????

    Q850's BIOS has a mode to disable half the cpu; will this pre-emp turbo boost?
