ROCK 5B
8K Single Board Computer with Quad Display
The ROCK 5B is a high-performance single board computer powered by the Rockchip RK3588 SoC, featuring an octa-core CPU (quad Cortex-A76 + quad Cortex-A55), Arm Mali-G610 GPU, and a 6TOPS-capable NPU for AI acceleration. It supports up to 32GB of LPDDR4x RAM and high-speed storage options including eMMC, NVMe SSD, and microSD. With four simultaneous display outputs—including dual HDMI 2.1 (up to 8K), DisplayPort over USB-C, and MIPI DSI—ROCK 5B is ideal for edge computing, multimedia applications, and development requiring 8K visuals. Built with rich I/O, AI capabilities, and open software support (Android, Radxa OS, Linux distros), it’s a versatile choice for powerful embedded solutions.
