NVIDIA recently released JetPack 4.4, so our team of Jetson Experts dug into this newest release to help you navigate upgrading your project.

This release builds on the 4.4 Developer Preview, supporting the latest member of the Jetson platform – the Xavier NX. In addition, JetPack 4.4 updates NVIDIA’s most popular libraries including production versions of CUDA, TensorRt, and cuDNN.  In general, the latest release results in better overall CNN/DNN inferencing performance across the entire Jetson platform. The updates to the CUDA 10.2, cuDNN 8 and TensorRT 7 resulted in an overall improvement in FPS as compared to JetPack 4.3, especially for larger models.
