I love the Jetson -- we have a bunch of them here -- but that's a SBC. What I want is an NVIDIA 2080Ti or 3080Ti card with some ARM cores that I can run apps that use CUDA+ARM directly on!
One has to wonder if at some point Nvidia will produce a PCIe carrier board or something for souped up Jetson modules or some variant. I have no idea how the connectivity (PCIe device?) would work out but it's definitely within the realm of possibility.
