The Nvidia Jetson TX2 board bears a Tegra X2 of microarchitecture GP10B. This board and the associated development platform was announced in March 2017 as a compact card design for low power scenarios, e.g. for the use in smaller camera drones. A matrix describing a set of performance modes was provided by the media along with that. Further a TX2i variant, said to be rugged and suitable for industrial use cases, is mentioned.
The Nvidia Jetson Xavier was announced as a development kit in end of August 2018Indications were given that a 20x acceleration for certain application cases compared to predecessor devices should be expected, and that the application power efficiency is 10x improved.
The Nvidia Jetson Nano was announced as a development system in mid-March 2019 The intended market is for hobbyist robotics due to the low price point. The final specs expose the board being sort of a power-optimized, stripped-down version of what a full Tegra X1 system would mean. Comparing in more detail only half of the CPU and GPU cores are present and only half of the maximum possible RAM is attached whilst the available or usable interfacing is determined by the baseboard design and is further subject of implementation decisions and specifics in an end user specific design for an application case.

The published operation modes of the Nvidia Jetson Nano are:
JetPack is a Software Development Kit from Nvidia for their Jetson board series. It includes the Linux for Tegraoperating system and other tools. The official Nvidia download page bears an entry for JetPack 3.2 that states: RedHawk Linux is a high-performance RTOS available for the Jetson platform, along with associated NightStar real-time development tools, CUDA/GPU enhancements, and a framework for hardware-in-the-loop and man-in-the-loop simulations.
The QNX operating system also available for the Jetson platform, though it is not widely announced. There are success reports of installing and running specific QNX packages on certain Nvidia Jetson board variants. Namely the package qnx-V3Q-23.16.01 that is seemingly in parts based on Nvidia's VibranteLinux distribution is reported to run on the Jetson TK1 Pro board.
