Linux support for NPUs is still evolving but making progress. Intel’s NPUs can be used with their OpenVINO toolkit (works on Ubuntu/Fedora), and AMD has their ROCm platform for their NPUs. You can run stuff like Stable Diffusion locally using these - check out Automatic1111 which can utilize NPU acceleration. If you’re looking for the best power efficiency for AI workloads, you might want to compare some power stations on gearscouts.com to keep your system running during longer inference sessions.
