Most cards work fine with fewer lanes available they just don't get as much bandwidth between the GPU and the CPU.īoth cards were recognized appropriately when I ran lspci, so at least there was a glimmer of hope: # Nvidia GeForce GT 710Ġ1:00.0 VGA compatible controller: NVIDIA Corporation GK208 (rev a1) (prog-if 00 ) You could hack off the bit in the middle to make the card physically fit, and it would work, but luckily there are x1 to x16 adapters that allow larger cards to plug into the x1 slot (though without the added lanes of bandwidth). Just getting the hardware to plug in might be your first challenge, as many (in fact, almost all) GPUs have physical slots that won't fit in the IO Board's x1 PCIe slot. which I found after trying to use it does not work with as old a video card as the one I tried!

Radeon open source driver (you have to recompile the Raspberry Pi OS kernel to enable it).Nouveau open source driver (you have to recompile the Raspberry Pi OS kernel to enable it).I have tried the following drivers, and all of them failed to initialize the card fully in one way or another: Partly it's due to lack of support for I/O BAR space on the BCM2711 ARM SoC, and partly it may be due to driver bugs or features that are only supported on X86 or certain ARM architectures. It also supports OpenGL ES 3.0, and it's not a terrible little GPU for what it costs.īut there are many people who have wanted to know whether you could use an Nvidia or AMD GPU with a Pi, and I have tried answering that question. The Pi's BCM2711 SoC includes a VideoCore 6 GPU capable of features like H.265 4Kp60 decode, H.264 1080p60 decode, and 1080p30 encode. And test I have! I am detailing all the cards I've tested and the results on my Raspberry Pi PCIe device compatibility database, and you can look at the linked issues to learn more about each card.

Now that the CM4's IO Board has a 1x slot, it's trivial to plug in any PCI Express card, and test out its functionality with the Raspberry Pi. Watch this video for more detail about my experience using these GPUs on the CM4: The slightly older Raspberry Pi 4 model B could be hacked to get access to the PCIe lane (sacrificing the VL805 USB 3.0 controller chip in the process), but it was a bit of a delicate operation and only a few daring souls tried it. The Raspberry Pi Compute Module 4 eschews a built-in USB 3.0 controller and exposes a 1x PCI Express lane.
