Introduce Rockchip RK3568

November 28, 2020

The RK3568 was officially unveiled in the fifth RDC(Rockchip Developer Conference).

Rockchip RK3568 chip is a high-range general-purpose SoC, made in 22nm process technology, integrated 4-core ARM architecture A55 processor and Mali G52 2EE graphics processor, supporting 4K decoding and 1080P encoding. RK3568 supports various types of peripheral interfaces such as SATA/PCIE/USB3.0, it has a built-in independent NPU, and can be used for lightweight AI applications. RK3568 supports both Android 11 and Linux systems, and targets at industrial customization markets such as IoT gateways, NVR storage, industrial control panels, industrial equipment, industrial control boxes, karaoke, cloud terminals, and vehicle control center.

Highlights 2: New generation(3rd Gen) Rockchip ISP

  • up to 8M@30fps processing power, suppporting time-sharing and multiplexing dual camera
  • Powerful HDR function makes the image clear under backlight or strong light conditions
  • Support dual channel simultaneous zooming output
  • Noise cancellation function, so that the image under low light conditions is also delicate
  • Support defogging function, can see clearly even in haze
  • Support lateral correction of LDCH to remove the distortion caused by the sensor lens

Hightlight 3: Powerful multimedia decode/encode capability

  • Support 4KP60 H.264/H.265/VP9 and other formats HD decoding
  • Support simultaneous decoding of multiple video sources
  • Support HDR10, excellent performance in color and dynamic range
  • Support image post-processing, deinterleaving, denoising, color enhancement, resolution increase
  • Support 1080p 60fps H.264 and H.265 format encoding
  • Support dynamic bit rate, frame rate, resolution adjustment

Hightlight 4: Integrated efficient RKNN AI processing unit

  • NPU with 1TOPs computing power
  • Embedded neural network hardware accelerator, support INT8, INT16, FP16 efficient operation
  • NPU hardware natively supports technologies such as pre-processing merging, channel quantization, and zero skipping
  • Support lossless compression of INT8, INT16, FP16 neural network parameters
  • The NPU core supports ordinary convolution, depth separable convolution, deconvolution, hole convolution, fully connected layer and pooling layer
  • NPU internal blocks include multiply-add operations, activation, LUT and precision conversion units, and support custom layer construction
  • Support one-click model conversion, support Caffe/TensorFlow/TF-Lite/ONNX/PyTorch/Keras/Darknet mainstream framework models


The difference between RK3566 and RK3568 is mostly the following:

  • RK3568 has an addtional 2 lanes PCIe 3.0, which can be splitted as two PCIe 3.0 x1 up to 8Gbps, making high speed expansion possible
  • RK3568 has native dual GbE ethernet, an essential features of many industrial application
  • RK3568 chip footprint is much bigger than RK3566 with more PINs and IOMUX possible, making product design more flexible
  • The cost for RK3568 is of course more expensive than RK3566
