macOS Notes

Sonnet's May 2026 compatibility table limits M-series Macs to non-GPU cards in this enclosure. Apple Silicon does not have an officially supported external-GPU graphics path.

Windows Notes

Sonnet supports the enclosure for eGPU use on Windows 11 25H2 or later. It accepts triple-wide cards up to 345 x 155 x 70mm.

NVIDIA Notes

No native macOS CUDA or supported Apple Silicon graphics path. Any TinyGPU/tinygrad compute experiment requires exact-stack validation.

AMD Notes

The ASUS Radeon AI PRO R9700 fits the published physical envelope, but macOS software support is not implied and must be reproduced before quote.
