The Orange Pi Zero 3W beats the Raspberry Pi 5 on paper, but it can't use half its own hardware

The Orange Pi Zero 3W is a compact, affordable SBC featuring an octa-core Allwinner A733, up to 16GB LPDDR5, a Vulkan 1.3-capable PowerVR GPU, and a 3 TOPS NPU — specs that rival or exceed the Raspberry Pi 5. However, Orange Pi's official Ubuntu image ships without the proprietary GPU userspace stack, leaving hardware acceleration, video decode, and the NPU demo broken out of the box. By transplanting the missing userspace libraries and kernel modules from Radxa's image for their Cubie A7S (which uses the same SoC), it's possible to get Vulkan, hardware video decode, WebGPU in Chromium, and the YOLOv5 NPU demo working. Several quirks remain, including a KMS cursor-trail bug requiring a software framebuffer workaround that breaks Firefox's GPU acceleration, and mpv lacking a compatible hardware decode backend for Allwinner's BSP stack.
