  1. 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.

  2. NVIDIA and Oracle Bring Vera Rubin and Vera CPUs to OCI

    NVIDIA and Oracle announced that Vera Rubin NVL72 systems and standalone Vera CPUs are generally available on Oracle Cloud Infrastructure Superclusters. They also plan to expand the Rubin deployment to multi-gigawatt scale and offer an HGX Rubin NVL8 configuration with eight GPUs, a dual Intel Xeon 6 host and 4 TB of DDR5 memory. The vendors say CPU and GPU resources can scale independently for model training, inference and agent workloads; Tom’s Hardware separately benchmarked Vera on a non-OCI server, so those results do not independently verify OCI production performance.

  3. Samsung and SK hynix reportedly ramp 8Hi HBM4 for NVIDIA Rubin Ultra

    Samsung Electronics and SK hynix reportedly plan to mass-produce and ship 8Hi HBM4 to NVIDIA in Q2 2027, with 8-layer supply for Rubin Ultra and standard Rubin increasing as 12-layer production remains active. The reports attribute the shift to the greater cooling and yield challenges associated with taller DRAM stacks. Wccftech assessed the claim as “Questionable,” noting that NVIDIA has not finalized whether Rubin Ultra will use 8Hi HBM4, HBM4E, or a mixed configuration.

  4. 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.
