At this point it's completely uninteresting for the price point.
It only has 276 GB/s memory bandwidth.
The dgx spark definitely makes sense for some people, but $3k for an upgraded Jetson, with less tops than a last gen consumer 4090, does beg the question. Unless you're getting them to practice specifically on nvidia hardware before scaling up, why not get an m4 max Mac w/ 128GB+ ram instead?
It'd be nice to know how this compares to what we can run locally on today's "AI" optimized machines from Apple, Microsoft, etc.
