    The 7700hq will definenitely outperform the 8550u IMO.

    Thx! I`ll give it a try when I install the game next time.

    Think so too! Still in games that demand high single core CPU clock the 8650u does quite well. I had some issues with Borderlands 2 on my 6700hq in CPU limited areas which I did not notice on my Surface Book 2. The performance in Grim Dawm is also very nice.

    Best regards

    P.S.: Has anyone tried to undervolt the GTX 1060 in their SB2 15"? I´d be curious to hear wo many watts this will save you...

    Mostly it will be locked. You can try it using MSI AB and see if it works. Don't forget to save profile after undervolting.

    Yes, thank you! I got the 1050 in my SB2 undervolted via Afterburner. It works very well. Still, I`d be interested in expreiences concearning the 1060.

    You have undervolted several Pascal notebook GPUs, right?

    Undervolting might not the very exact term, but yes: Afterburner (ctrl+f) allows to set the relation between "mV" and "mhz" (nvidia Pascal) and thus allows to run the craphics card with a lower mV/mhz-ratio. For my SB2 got two settings:

    Power saving -> with the base voltage of 800mv I achive a fixed 1278mhz

    Performance -> with a voltage of 925 mv I achive a fixed 1798mhz (about 100mv less than the card would draw at stock clocks)

    Taking this into regard, I think the SB2 15 inch 1060 draining issue, could be somewhat diminished by undervolting the GPU.

    Best regards

    Use a bigger AC adapter like 180W.
    Use nvidia inspector to turn on battery boost that will reduce the chance of pulling additional power from battery by limiting FPS to 30.
