Nvidia's Vera Rubin NVL72 specification table lists one Rubin GPU at 288 GB of HBM4 and 19.2 TB/s, with 3 TB/s of NVLink. The HGX page's individual-GPU row still lists 288 GB, 22 TB/s and 3.6 TB/s of NVLink, while its eight-GPU system row lists 2 TB of HBM4 and 130 TB/s. ServeTheHome wrote on Oct. 31 that the lower per-GPU figures replaced preliminary specs, and Nvidia has not explained the difference on these pages.
