Todd Dailey(@twid):I missed in the Microsoft announcement yesterday that the Microsoft Surface RTX dev box lacks the connectx-7 network interface you'll find in pretty much every other DGX spark box. This limits you to a single dev box, since clustering over 10Gb ethernet is 20x slower, less efficient, and not really practical. Given the number of great 2, 3, and even 4x spark recipes from @MiaAI_lab and others this is a pretty big downgrade that limits future expandability.
