Pineboards, a manufacturer of expansion boards for Raspberry Pi, showcased the advancements in PCIe support with the Pi 5. With one of their products, the company connected an AMD Radeon graphics card to the Raspberry Pi 5 and successfully played a fully 3D open-source game.
According to Pineboards, setting up the system took about an hour. It was created based on the Raspberry Pi 5 with the HAT uPCIty Lite board. This board allows any PCIe card to be connected to the corresponding PCIe bus on the Raspberry Pi 5. The computer features one PCIe x4 slot, which is open—meaning that a x16 card can also be connected.
In their experiment, they utilized an AMD Radeon RX 460 (apparently from Gigabyte). An ATX power supply, be quiet! with a capacity of 400W, was used to power the graphics card. After applying "some minor driver fixes" provided by Coreforge, Pineboards managed to play the 3D racing game SuperTuxKart with full 4K display support.
Got it working!

The Raspberry Pi 5 has addressed previously reported issues with the bus by enthusiasts, but there was a challenge with Linux GPU drivers for ARM. With substantial assistance, countless hours of debugging, and perseverance, YouTuber and journalist Jeff Geerling was able to get the Radeon RX 460 functioning and run some tests in glmark2, but gaming remained out of reach.
As seen in the video, SuperTuxKart runs smoothly on the assembled system. Recently, the community has made numerous improvements to the Linux kernel drivers for Raspberry Pi 5, and Pineboards highlighted exciting changes in their operation.
