RK3568 is a high-performance and low power quad-core application processor designed for personal mobile internet device and AIoT equipments.

Many embedded powerful hardware engines are provided to optimize performance for high- end application. RK3568 supports almost full-format H.264 decoder by 4K@60fps, H.265 decoder by 4K@60fps, also support H.264/H.265 encoder by 1080p@60fps, high-quality JPEG encoder/decoder.

Embedded 3D GPU makes RK3568 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/FP16/BFP16 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.

RK3568 has high-performance external memory interface(DDR3/DDR3L/DDR4

/LPDDR3/LPDDR4/LPDDR4X) capable of sustaining demanding memory bandwidths.
