As expected, usually the more you spend on a board, the better the performance and features. The exception is Jetson TX2 which’s the same price as the new Jetson Xavier NX devkit but delivers about a fifth of the FP16 AI performance. So as today, there’s little reason to buy a TX2 board for a new project unless you need some of the required features that are missing on Xavier NX.
