    The TB3 INTERFACE has Tb3 to pcie conversion overheads. The GA interface is basically a powered m.2 ngff extension cable with a proprietary connector.

    Yeap.
    But once you start pushing 1440p or above ,the gap becomes less.

    Its an actual pci express 3.0 4x slot with a cable attached. Because there are not enough lanes available the internal gpu is operating at 8x speeds.

    So with the GA it reduces the internal GPU bandwidth to x8 from x16?

    Well it is reduced by 8X anyway with or without the GA connected. THey just have split the lanes hardware wise. Not that it matters a lot. The 980M is not bottlenecked in my cased by 8X but it cant go higher than 8X with the AGA disconnected.

    The config is 4x for the AGA, 8X for the GPU, 4x for the first M2 slot, 2X for the second M2 slot. Unsure what the TB3 can utilize.

    That's what the m.2 port also gets.
    But if it was an actual port, then people wouldn't be having issues with the latest drivers.

    The possible driver problems is because of the software control that disables the internal GPU when the AGA is connected with a supported GPU.

    I can make photo for your of the AGA PCB later if you want. The patch suggest it is a fairly straightforward solution.

    If possible PM me with the info. But people have been getting code 43 issues with the 1070 . Same as other mPCIe / m.2 eGPU users. For others with the cards over MXM , things are fine.
    Do you have images of the motherboard with the port by any chance?

    I can make some later tonight when I am back home.

    I knwo with the latest Nvidia drivers there are som eproblems using the 1070 externally. Might that be why the code 43 issue appears?
