  1. 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.
