Hi there!
I'm evaluating using a laptop of the above model for higher end machine learning (using fairly large images), so I would like to use something like the Nvidia GTX 1080, and that laptop is additionally right in my price range (< 30k EUR).

But I need to be able to push data fast enough to the graphics card, so I'm wondering how many PCI lanes are available to the graphics card - both a priori, with factory standards, and considering any possible modifications.

I didn't manage to find any information about the mainboard that would provide an answer to my question. Where are the super duper technical facts about the laptop hidden, like setup of internal buses? : )

Cheers!

    Have figured out just now that the mainboard is (probably) a mobile iontel HM175 - which supports max 16 PCI lanes.

    I guess I can reformulate my question now to what is the maximum number of PCI lanes usable for the graphics card on that board, and under which configurations / prerequisites?
    Is it possible to use all 16 if the SSD drive is removed / configured to not use PCI lanes?

    From my G9-793 with GTX 1070 16 lanes are available to the dGPU
