Raspberry Pi 4 Model B vs Rock Pi 4 Model B
Side-by-side comparison of features, pricing, ratings, and alternatives.
The Raspberry Pi 4 Model B represents a major leap forward in the popular single-board computer range, offering desktop-class performance that rivals entry-level x86 PC systems. Equipped with a high-performance quad-core processor and flexible memory options, it empowers users to build everything from smart home automation hubs to media centers and edge AI devices. Featuring true dual-monitor support at resolutions up to 4K, upgraded USB 3.0 ports, and genuine Gigabit Ethernet, this iteration provides the robust I/O capabilities required for demanding projects. Its active developer community and vast ecosystem of compatible HATs and accessories make it the definitive platform for learning to code and prototyping hardware inventions.
The Rock Pi 4 Model B is a single‑board computer built around the Hexa‑core Rockchip RK3399 processor, offering up to 4 GB LPDDR4 RAM, dual‑channel eMMC, and a full‑size HDMI 2.0 port for 4K@60Hz output. Its compact 85 mm × 56 mm board includes USB‑C Power Delivery, USB‑3.0, Gigabit Ethernet, Wi‑Fi 802.11ac and Bluetooth 5.0, making it suitable for both headless servers and media‑center projects. Designed for hobbyists, developers, and edge‑AI applications, the Rock Pi 4 supports Linux, Android, and various open‑source OS images. The board’s GPIO header, PCIe‑x1 lane (via M.2 slot), and optional carrier boards enable expansion into robotics, AI inference, and networking appliances.
