What is rk3566?

RK3566 is a new system-on-chip (SoC) designed and manufactured by Rockchip, a leading Chinese semiconductor company. It is a powerful and energy-efficient chip that targets mid-range and high-end multimedia applications, including smart TV, set-top box, OTT box, and AIoT devices.

RK3566 is based on a 64-bit quad-core Arm Cortex-A55 CPU architecture, running up to 2.0 GHz, combined with a Mali-G52 GPU with up to 800 MHz frequency. It supports DDR4/LPDDR4 memory, up to 8 GB, and various storage solutions, including eMMC 5.1, UFS 2.1, and SD 3.0. It also includes a rich set of interfaces, such as USB 3.0/2.0, PCIe 2.0, Gigabit Ethernet, HDMI 2.0a, and 4K@60fps video decoding and encoding up to H.265 and VP9.

RK3566 also features Rockchip's proprietary NPU (Neural Processing Unit) for AI acceleration, enabling efficient and accurate inference for a wide range of AI applications, such as face recognition, image and speech recognition, and natural language processing.

Overall, RK3566 represents a significant upgrade in performance and features compared to its predecessor, RK3326, and positions Rockchip as a leading provider of multimedia and AI solutions in the market.
