RK3566 Overview

RK3566 has very powerful video decoding capabilities. It supports 4K H.264/H.265/VP9 and other formats of high-definition decoding, and supports simultaneous decoding of multiple video sources, such as 8 to 10 channels of 1080P30 H264/H265. RK3566 supports HDR10, with excellent performance in color and dynamic range. It supports image post-processing, de-interleaving, denoising, color enhancement, and super-resolution. RK3566 adopts a new independent JPEG decoding processor, efficiently and concurrently processes multiple small image analysis, supports 1080p 60fps H.264 and H.265 format encoding, supports dynamic bit rate, frame rate, resolution adjustment and other functions.

Embedded 3D GPU makes RK3566 completely compatible with OpenGL ES 1.1/2.0/3.2,
OpenCL 2.0 and Vulkan 1.1. Special 2D hardware engine will maximize display performance
and provide very smoothly operation.

The build-in NPU supports INT8/INT16 hybrid operation. In addition, with its strong compatibility, network models based on a series of frameworks such as TensorFlow/MXNet/PyTorch/Caffe can be easily converted.

RK3566 has high-performance external memory interface(DDR3/DDR3L/DDR4/LPDDR3/LPDDR4/LPDDR4X) capable of sustaining demanding memory bandwidths.
