The Orange Pi 6 Plus arrives with serious hardware ambitions. It runs the CIX P1 SoC, a 12-core ARM chip with a Mali G720 GPU and a dedicated Zhouyi NPU that together claim 45 TOPS of computing power. That SoC comes from CIX Technology Group, a Chengdu-based fabless semiconductor company founded in 2021 by former Rockchip engineers. The board also packs 16GB of RAM and dual 5GbE Ethernet ports. Specs that read more like a small server than a hobbyist SBC. It's aimed at edge AI and homelab use, not weekend tinkering.
Rui Carmo, who reviewed the board over two months, skipped the vendor images entirely. He forked orangepi-build to create custom Debian 13 images with GPU and NPU support baked in from the start. That decision wasn't optional. Vendor images for boards like this boot fine but fall apart when you need trustworthy package sources or deterministic first boots. Working with the 6.6.89-cix kernel and Cix Technology Group's UEFI 1.3 for boot management, Carmo still had to patch GRUB configs, fix partition resize logic, and hunt through vendor components to get something reliable.
For AI inference, Carmo tested llama.cpp, PowerInfer, and ik_llama. The winner: Qwen 3.5 4B on llama.cpp with Vulkan, the most stable setup he found for running transformer models on hardware. Community feedback on the review noted that NPUs industry-wide still need work, especially on objective accuracy comparisons instead of raw speed metrics.
The CIX P1 is a direct shot at Rockchip's RK3588, the chip dominating ARM SBCs right now. Newer Cortex-A720 cores hit 2.6GHz, and the big.LITTLE architecture makes sense for server workloads. But Carmo's two-month ordeal shows the gap between specs and usable software remains wide. Anyone considering this board for edge AI should expect to spend real time in the build tree, not just flash an image and go.
