The RK3399 is a low-power, high-performance application processor chip from Rockchip. The chip is based on the Big.Little architecture, a dual-core Cortex-A72 and quad-core Cortex-A53 combination architecture with independent NEON coprocessors. It is mainly used in intelligent terminal devices such as computers, personal Internet mobile devices, VR, and advertising machines.
The RK3399 includes multiple high-performance hardware processing engines that support video decoding in multiple formats, such as H.264/H.265/VP9 for 4K*2K@60fps and H.264/MVC/VP8 for 1080P@30fps. And high-quality JPEG codec and image front and rear processors.
