Key Features in JetPack 4.3 Developer Preview

JetPack 4.3 DP introduces TensorRT 6.0.1 and cuDNN 7.6.3.


NVIDIA L4T provides the bootloader, Linux kernel, necessary firmwares, NVIDIA drivers, sample filesystem, and more.

JetPack 4.3 DP Highlights:
  • L4T 32.2.2 features are unchanged from L4T 32.2.1 (included in JetPack 4.2.2) except:
    • support is added for TensorRT 6.0.1 and cuDNN 7.6.3
    • only Jetson AGX Xavier Developer Kit is supported

For details, see L4T 32.2.2 release notes.


TensorRT is a high performance deep learning inference runtime for image classification, segmentation, and object detection neural networks. It speeds up deep learning inference as well as reducing the runtime memory footprint for convolutional and deconv neural networks.

JetPack 4.3 DP Highlights:
  • New layers, operators, and resize operations
  • New samples
  • New optimizations

For details, see TensorRT 6.0.1 for Jetson platform release notes.


CUDA Deep Neural Network library provides high-performance primitives for deep learning frameworks. It includes support for convolutions, activation functions and tensor transformations.

JetPack 4.3 DP Highlights:
  • Tensor Core Support and performance enhancements for 3D convolutions, grouped convolutions, and more
  • Performance enhancements for 3D deconvolution
  • Enhanced functionality for fused operations

For details, see cuDNN 7.6.3 release notes.
