This information appears to be coming via the hacked confidential data stolen from Nvidia a few days ago. The images show driver code mentioning six Ada Lovelace SKUs, two Hopper SKUs and two more Blackwell SKUs. Judging by the number of SKUs, Ada Lovelace is clearly Ampere's successor, and we already knew that Hopper is targeting data centers, but it is still unclear what Blackwell is bringing to the table.
