   NVIDIA Revises Vera Rubin Specifications for Volume Production

   NVIDIA said the revised Vera Rubin specifications represent what its systems sustain after qualification and volume production, rather than the preliminary architectural targets published during development. The changes lower the per-Rubin GPU HBM4 bandwidth from 22 TB/s to 19.2 TB/s and NVLink 6 bandwidth from 3.6 TB/s to 3 TB/s across the platform. NVIDIA also said Vera Rubin NVL72 is shipping and that published third-party agentic benchmarks used the production specifications, but the supplied reports do not independently verify those claims.

   Meta details Prometheus, an Ohio supercluster heading toward 1 million GPUs

   Meta published engineering details of its Prometheus supercluster in New Albany, Ohio, saying it already runs hundreds of thousands of Nvidia GPUs across several buildings and is planned to grow to roughly 1 million operating in lockstep. The first gigawatt-scale phase is finished and was used to train Meta's Muse family of models, including Muse Wonder, on Nvidia GB200 NVL72 and GB300 NVL72 racks, with Vera Rubin NVL72 planned for a third platform. Meta says a year of engineering cut training interruptions by 99%, from nearly 1,000 per 8,000 GPUs per day in mid-2025 to about 11, and that each 72-GPU rack trains on a 64-GPU slice with eight GPUs kept as spares.
