NVIDIA has just announced Jetson Xavier NX system-on-module, with the company claiming it is the “world’s smallest, most powerful AI supercomputer for robotic and embedded computing devices at the edge” with a 70x45mm “Jetson Nano” form factor, and delivering either up to 14 TOPS at 10 Watts or 21 TOPS at 15 Watts.
The Jetson Xavier NX board features an Nvidia Volta GPU AI accelerator with 384 CUDA cores and 48 tensor cores, with two Nvidia deep learning accelerators. Its CPU is a 6-core Nvidia Carmel Arm 64-bit CPU.
The company expects the module to be used in small commercial robots, drones, intelligent high-resolution sensors for factory logistics and production lines, optical inspection, network video recorders, portable medical devices, and other industrial IoT systems.
Jetson Xavier NX Specifications:
- SoC – NVIDIA Xavier with 6-core NVIDIA Carmel ARM v8.2 64-bit CPU,
6MB L2 + 4MB L3 caches, and a 384-core NVIDIA Volta GPU with 48 Tensor Cores, 2x NVDLA deep learning accelerators delivering up to 21 TOPS at 15 Watts
- System Memory – 8 GB 128-bit LPDDR4x @ 51.2GB/s
- Storage – 16 GB eMMC 5.1 flash

Like other Jetson boards and modules, Jetson Xavier NX runs Ubuntu-based Linux, is supported by NVIDIA JetPack software development kit, and CUDA-X AI libraries. The module supports all most common AI frameworks such as TensorFlow, PyTorch, MxNet, Caffe, and others.
In a world where AI chips are announced on what seems like a daily basis, I believe NVIDIA raised the bar with its Jetson Xavier NX — showing that exceptional performance at small size and low power, together with a consistent and powerful software architecture, is what matters in embedded edge computing.
There’s no Jetson Xavier NX development kit, but since the SoM is pin-compatible with Jetson Nano, so you should be able to reuse/upgrade existing carrier boards. In order to get started quickly, the company invites developers to begin application development using the Jetson AGX Xavier Developer Kit with a software patch emulating Jetson Xavier NX.
