Rock Pi 4 vs BeagleBone Black
Side-by-side comparison of features, pricing, ratings, and alternatives.
The Rock Pi 4 is a compact single-board computer featuring a hexa‑core Rockchip RK3399 processor, up to 4 GB LPDDR4 RAM, and dual‑channel M.2 NVMe support. It offers a rich I/O set including dual HDMI 4K, USB‑C 3.0, Gigabit Ethernet, and Wi‑Fi/Bluetooth for versatile connectivity. Designed for developers, makers, and edge‑AI projects, the board runs Linux, Android, and various open‑source OSes, providing a flexible platform for everything from media servers to AI inference workloads.
The BeagleBone Black is a low-cost, community-supported development platform featuring an AM335x 1GHz ARM Cortex-A8 processor. It runs full-featured Linux distributions and offers extensive expansion capabilities through dual 46-pin headers. Designed for hobbyists, educators, and embedded developers, the board integrates 512MB of DDR3 RAM and 4GB of on-board eMMC flash storage preloaded with Debian. Its unique Programmable Real-Time Unit (PRU) subsystems allow for deterministic, low-latency real-time I/O operations.
