B300 vs RTX PRO 6000: price per hour and cost per token
Blackwell Ultra: twice the H200’s memory, so one node of 8 holds the largest open models with room for long contexts. Blackwell workstation and server card: more memory than an H100, usually for less per hour, but no NVLink, so best when a model fits on one.
