The first problem with doing this is that there is no driver support for using an NVIDIA or AMD / ATI GPU on an ARM based device. Not that it isn't possible, just not supported on external cards yet. For example, thhe NVIDIA Jetson class systems are a system on chip with an ARM CPU core coupled with a GPU.
The second is hardware support. PCIe slots intended for GPUs supply 75Watts to the GPU while the rest of the GPU's power is supplied by the 12V connector. PCIe x4 connectors are not intended for GPUs and are often only designed to provide up to 45 Watts. I don't know if this is the case for the RockPro64, but it is a potential problem area.
If you can get your AMD GPU to power up there is some hope. I have heard that there are efforts to port the open source AMD / ATI driver to ARM. In addition, Samsung may be adopting AMD GPU's for Android and Chrome OS devices.
Okay thank you.
I saw on the nvidia page a driver for Linux ARM 32 bit. I will test it and I ask nvidia for an interface drawing to soldering the power supply on the PCIE of the GPU.
If its work I will answer and if you like I can post a tutorial for a reconstruction on this page.
