Radxa, a Brazilian developer of single-board computers (SBCs), has started sales of its Rock Pi 4C SBC that is designed for ultra-cheap ultra-compact systems.
The Radxa Rock Pi 4C SBC is based on the Rockchip RK3399 system-on-chip (SoC) that was originally designed for inexpensive Google Android tablets and therefore has a rather decent feature set and performance. The board could potentially power an entry-level home-theater or entertainment PCs project or a ‘typewriter-class’ office PC that does not need significant performance.
The Rockchip RK3399 SoC packs two high-performance Arm Cortex-A72 cores running at up to 1.80GHz, four energy-efficient Arm Cortex-A53 cores operating at up to 1.40GHz, Arm Mali-T864 GPU, as well as a multimedia engine that supports hardware decoding of modern video codecs used by streaming services, including MPEG-1, MPEG-2, MPEG-4, H.263, H.264/MPEG4-AVC, H.265/HEVC, VC-1, VP9, VP8, and MVC.
