Anecdotally, a friend has been using TX2s and got a Xavier to test out. He was blown away by the performance delta. It’s got an octocore ARM for a CPU, and while I don’t recall what the TX2 has... that’s a lot of CPU cores to work with.

I’ve got a Xavier sitting on my desk too, but haven’t played with it much. Running OpenCV on it and doing some light live video processing was really smooth.

For games you usually want smaller number of high performant cores than many lesser performant. Haven't done much game programming in recent years, but I still remmember the terror of programming PS3 Cell CPU.

Were the CPU cores of Cell (PPEs) hard to program? I had the impression that the difficulty of the Cell was in the need to manage the 8 SPEs, not in writing software for the Power4 core.

The 8 core Carmel CPU in Xavier is not like the SPEs in Cell.

It was hard to utilise all those cores. I am sure game architectures evolved during the years, but back then we didn't know how to split the code to optimally utilise all available resources.
