The exposed PCIe lanes looks like the killer here. I guess you can now do 2.5GBe, NVMe drives, beefier GPUs, and other fun things?

- 0-_-0 6y agoIIRC the PCIe interface is not compatible with GPUs.
- geerlingguy 6y agoIt may be, but nobody has proven it yet... the biggest issue is lack of ARM video drivers :( I might pick up an older PCIe card and see how far I can get using it with the CM4.
- 0-_-0 6y agoI think it's proven it doesn't work because the RPi CPU doesn't have enough BAR (Base Address Register) space. More details in this discussion: https://news.ycombinator.com/item?id=20399652 https://news.ycombinator.com/item?id=20399652
- the_only_law 6y agoI have a project where I was going to build a full x86 machine to serve as a domain specific server because the HW interface I need is only available in PCI amd PCIe cards. Wonder if I could hack the drivers to work on one of these.
