Test AMD RX 7900 XT with Pi 500+
As the title says... I had tested the XTX back before I returned it for having a defective vapor chamber in #503. Would like to see how the XT performs, as it might be the best value (bang for the buck) AMD card in 2025, if the VRAM meets your needs. It's also readily available anywhere, unlike some other model GPUs.

I installed the firmware for this card with:
# Install the base AMD GPU firmware
sudo apt install -y firmware-amd-graphics
# Reboot so the Pi can load the firmware
sudo reboot
It looks like all the right firmware is included in the firmware-amd-graphics package now, unlike how it was when I was initially testing the W7700...

It's working! Got display output at 60 Hz through HDMI and everything. No stutters, no artifacts, very nice!
Card is on the site here: https://pipci.jeffgeerling.com/cards_gpu/amd-radeon-rx7900xt-20gb.html
I installed Steam via Pi-Apps/Box64, and it seems to work well. I was able to play Horizon Chase Turbo, but Portal 2 wouldn't launch. SuperTuxKart of course plays perfectly.
