   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.

   NVIDIA Revises Vera Rubin Bandwidth Specifications

   IT之家 and Wccftech reported that comparisons between archived and current NVIDIA pages show lower HBM4 and sixth-generation NVLink bandwidth figures for several Vera Rubin configurations, alongside higher scale-out networking bandwidth. For the Rubin GPU, the published HBM4 bandwidth changed from a maximum of 22 TB/s to 19.2 TB/s, while NVLink 6 bandwidth fell from 3.6 TB/s to 3 TB/s. The changes also cover the Vera Rubin Superchip, NVL72 and HGX Rubin NVL8 systems. NVIDIA has not publicly explained the revision, and some product and regional pages still show older specifications. These are published specification changes rather than measured benchmark results, and the earlier 22 TB/s figure was a maximum, so the revision does not necessarily represent an equivalent decline in real-world performance across every configuration.
