RK3399

Rockchip RK3399 SoC integrates dual-core Cortex-A72 and quad-core Cortex-A53 with separate NEON coprocessor, and with ARM Mali-T864 GPU.

Overview

RK3399 is a low power, high performance processor for computing, personal mobile internet devices and other smart device applications. Based on Big.Little architecture, it integrates dual-core Cortex-A72 and quad-core Cortex-A53 with separate NEON coprocessor.
Many embedded powerful hardware engines provide optimized performance for high-end application. RK3399 supports multi-format video decoders including H.264/H.265/VP9 up to4Kx2K@60fps, especially, H.264/H.265 decoders support 10bits coding, and also supports H.264/MVC/VP8 encoders by 1080p@30fps, high-quality JPEG encoder/decoder, and special image preprocessor and postprocessor.
Embedded 3D GPU makes RK3399 completely compatible with OpenGL ES1.1/2.0/3.0/3.1, OpenCL and DirectX 11.1. Special 2D hardware engine with MMU will maximize display performance and provide very smooth operation.
RK3399 has high-performance dual channel external memory interface (DDR3/DDR3L/LPDDR3/LPDDR4) capable of sustaining demanding memory bandwidths, also provides a complete set of peripheral interface to support very flexible applications.
