Expert Summary

The Radxa Dragon Q8B is essentially a laptop operating in an SBC form factor. The Qualcomm Snapdragon 8cx Gen 3 System-on-Chip (SoC) is running 4 Cortex-X1 cores at 3GHz, and a further 4 Cortex-A78 cores running at 2.5GHz. At the time of testing (in May 2026), it was the fastest single board computer to go through our test benches. Will it retain its throne?

Multiple benchmark runs available. Perfect for seeing how different OS versions, kernels, and carrier boards may impact performance numbers. For example, Raspberry Pi OS vs Ubuntu on the Raspberry Pi 5, or official vs third-party carrier boards for your CM5.
