NVIDIA launched the Jetson Xavier NX developer kit yesterday, and I included a short comparison table in the announcement between Jetson Nano, TX2, Xavier NX, and AGX Xavier developer kits. But I thought it might be worthwhile to have a more detailed comparison in a separate post, so here we are.

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.

…and it’s worth noting that there’s very little in the way that’s missing from the TX2 to the Xavier NX…
The WiFi/BT is a Cypress part on the X2 SOM. You can put a better/more premium part for a little extra costs on the PCI-E edge.
