> If NVidia wanted their GPUs to work on Raspberry Pi, then it would already be done. It wouldn’t be an issue. But NVidia doesn’t care, because that’s not a real market for their GPUs. It's weird af that Geerling ignores nVidia. They have a line of ARM based SBCs with GPUs from Maxwell to Ampere. They have full software support for OpenGL, CUDA, and etc. For the price of an RPi 5 + discreet GPU, you can get a Jetson Orin Nano (8 GB RAM, 6 A78 ARM cores, 1024 Ampere cores.) All in a much better form factor than a Pi + PCIe hat and graphics card. I get the fun of doing projects, but if what you're interested in is a working ARM based system with some level of GPU, it can be had right now without being "in the shop" twice a week with a science fair project. |

“With the PCI Express slot ready to go, you need to choose a card to go into it. After a few years of testing various cards, our little group has settled on Polaris generation AMD graphics cards.
Why? Because they're new enough to use the open source amdgpu driver in the Linux kernel, and old enough the drivers and card details are pretty well known.
We had some success with older cards using the radeon driver, but that driver is older and the hardware is a bit outdated for any practical use with a Pi.
Nvidia hardware is right out, since outside of community nouveau drivers, Nvidia provides little in the way of open source code for the parts of their drivers we need to fix any quirks with the card on the Pi's PCI Express bus.”

I’m not in a position to evaluate his statement vs yours, but he’s clearly thought about it.
