Dragon Q8B Packs Edge AI, Dual 2.5GbE, and Triple 4K Output

Dragon Q8B Qualcomm Snapdragon SBC

Radxa has introduced the Dragon Q8B, a compact Qualcomm Snapdragon SBC designed for edge AI, robotics, industrial automation, and intelligent vision applications. The board measures only 100 × 75 mm and combines the Qualcomm Snapdragon 8cx Gen 3 Compute Platform with dual 2.5GbE networking, multiple PCIe expansion interfaces, and support for up to three 4K displays.

Built on Qualcomm’s 5nm Snapdragon 8cx Gen 3 processor, the Dragon Q8B integrates an octa-core Kryo CPU with four Cortex-X1-based Kryo Prime cores clocked at up to 3.0 GHz and four Cortex-A78-based Kryo Gold cores running at up to 2.42 GHz. The platform also includes an Adreno 690 GPU and Qualcomm AI Engine that delivers up to 29 TOPS of AI performance for machine vision, speech processing, automation, and compact LLM workloads.

Previously, we have covered several Radxa SBCs, including the Rockchip RK3588-based Radxa ROCK 5 ITX+, the compact Radxa Cubie A5E, the Nano-ITX form factor Radxa Orion O6N powered by the Cix P1 (CD8160) SoC, and the Radxa Dragon Q6A Edge AI SBC.
