10W Raspberry Pi 4 And 230W RX 6700 XT
This activity at Hackaday shows how the Raspberry Pi is evolving, as long as you intend to put a little work. Using the Raspberry Pi compute module, which incorporates a single PCI-e software with a single PCIe module and controls both GPUs and Raspberry Pi with ATX PSU Jeff Geerling was able to create both devices for communication.
The Raspberry Pi 4 has another ground plane, which means they need to use an adapter to make sure both devices are receiving pure power, which they won. They also need a PCIe adapter for connecting the x16 GPU and x1 PCIe component so that the compute unit with the RX 6700 XT can be connected.
Jeff set up a Linux version and tried to create a kernel using AMD Linux drivers, which did not work well, but for reasons he believed he could handle. He talks about his troubleshooting work including the demolition of Pi memory to PSP memory training for the GPU but the point is that they communicate.
You haven’t played Crysis this time anytime soon, but by reading the heavy workload it will greatly help you Raspberry Compute software and teach you more about PCIe bus, memory sharing and Raspberry Pi 4 skills.
