Has Anyone Successfully Linked a Quadro RTX 6000 in an eGPU Case to a Jetson AGX Xavier?

Hi everyone,

I’m exploring the possibility of connecting a Quadro RTX 6000 GPU housed in a Razer Core Chroma eGPU enclosure to a Jetson AGX Xavier. Since the Jetson platform doesn’t natively support Thunderbolt (which the Razer Chroma uses), I am considering using the PCIe Gen4 x8 slot available on the Xavier for this purpose.

Before I dive deeper into the hardware and software setup, I wanted to ask:

Has anyone successfully attempted a similar setup before, either with the Quadro RTX 6000 or another GPU in an eGPU enclosure, on the Jetson platform?
Is this approach feasible in terms of driver compatibility (e.g., CUDA and NVIDIA driver support for ARM64) and hardware connectivity?
Are there specific challenges or workarounds that I should be aware of, such as power delivery, PCIe bandwidth limitations, or kernel modifications?
I’m primarily looking to use the RTX 6000 for high-performance computing tasks (e.g., deep learning inference and model training) alongside the Xavier.

Any insights, suggestions, or similar experiences would be greatly appreciated! Thanks in advance.

Won’t work. The drivers in the Jetson are for the integrated GPU (iGPU) which is wired directly to the memory controller, whereas most other GPUs are discrete GPUs (dGPU) with a PCI bus connection. The two conflict. I also think there would be issues with any non-PCI based approach even if the two drivers would not conflict. Note that the ARM64 drivers you see for data warehouse hardware will not be compatible with an iGPU.

I could see the possibility that some future Orin or newer product could possibly have this ability, but at the moment, I think you’re out of luck on that.
