    Why do some laptops have 2 GPU's?


    I'm really sorry if this is kind of a n00b question, but why do some laptops come with na integrated intel GPU and an optional Nvidia Geforce?

    I'm looking for a good performance laptop, to work with Vegas Pro and other heavy apps, and I found this sweet machine...expensive, but still sweet xD
    But what really grinds my gears is the Intel + Nvidia combination. Why do some laptops come with two GPU's? Would such a combination result in combatility issues? Is it to choose which one to use, or does it use both for a more powerful result?

    I'd appreciate some info on this, can't seem to find it online.

    Thank you for your time.

    because the integrated GPU isn't good enough for some games or high end apps and some people prefer dedicated graphics and not integrated so they offer NVidia GPU as an optional extra. also the intel GPU is integrated into motherboard, NVidia one isn't

    you will only use one GPU though.

    there will be no conflicts and will only one gpu at a time for best results ,as already said it will use the Nvidia Geforce for more intense graphics and games

    It is all about reducing power consumption and improving run time on battery power. The Intel GPU has lower performance and power consumption and is used for general use. When needed the higher performance Nvidia GPU will be used. By their nature high performance video GPUs require more power, whether the performance is currently needed or not.

    Much of the design of Laptops centers around keeping power consumption down.

    Owh, ok. Thank you so much for the replies, guys =D

    Sounds great, if it really doesn't hurt graphical performance. But there's always a way to preset one of the GPU's to do everything at all times, right?

    Some laptops come with APU's. The CPU and GPU are on the same die, all in the one chip. Then they add a dedicated GPU as an option for better performance. My ASUS laptop has an AMD A-10 APU plus an ATI HD 7670M. I can chose what programs use what GPU and it can switch on the fly. The 7670M has 1 gig of dedicated video RAM. The 7660G in the A-10 APU will run cooler and draw less power. Having the option to chose which one you want it just a bonus feature.

    There would be no need to have an option for this...and why would you want one? Even if you were running on AC power, the laptop would produce less heat and draw less power using the onboard graphics for normal tasks, extending the life of the internal components. For example, if you were browsing this forum, why would you want or need the Nvidia graphics chip running?

    When you need the extra graphics power, it kicks in automatically. There would ne need or reason to have it run any other way. The onboard graphics are more than enough to handle regular tasks.

    There Is supposed to be some kind of Combo Dedicated/Integrated Video setup. That's why there are 2 GPUs, but they act as one.
