I'm waiting for someone to use the Ubuntu image and compile a custom kernel with AMD GPU support.

Then, you could put a real GPU in there. Even though it'd be limited by just a x1 PCIe 2.0 link, I'm sure even a RX 550 would still run circles around the Pi's integrated VideoCore GPU!

The Pi's GPU is definitely one if its weakest aspects, in the current generation.

That does not go though the usb translation twice then it makes a bit of sense,
but if its sent though that port -> usb protocol -> backward translation -> pcie
then the lag on this must be making it pointless.

LOL. I mean, it's inevitable, right? Someone will almost certainly do this. The CPU in the Pi is also going to be a limiting factor, but I'm looking forward to someone posting Pi + RX 5700 XT performance results. "I bought a $50 Pi, then attached a $375 GPU to it via a $25 adapter setup!"
