   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.

   Musk: SpaceX-Nvidia Star Mind AI satellite computer to enter volume production next year

   Elon Musk said in an Oct. 15 post on X that the Star Mind AI computer co-engineered by SpaceX and Nvidia is "far better than almost anyone expects" and will reach volume production next year, while the TechNews article body dates volume production to 2027. According to information Nvidia previously published, SpaceX is advancing the Star Mind satellite computing system using a space-optimized Vera Rubin NVL72 architecture combining Vera CPUs and Rubin GPUs to extend high-performance AI computing from ground data centers into orbit. Citing foreign media, the report says the first custom satellite built for the space environment is expected to launch in the fourth quarter of 2027, with scaled operation hoped for in 2028, though the technology remains in development and actual specifications and commercial benefits are unconfirmed.

   HPE confirms Nvidia will offer a Rubin PCIe GPU

   According to a presentation HPE shared with The Next Platform and other outlets, HPE has confirmed that its ProLiant DL585a Gen13 server supports an Nvidia Rubin PCIe GPU. The existing Rubin GPU is a data-center part in the SMX form factor drawing up to 2300W, so the report says using that version in a PCIe card would require at least halving the GPU's scale and sharply reducing clocks; the PCIe part could instead sit in the RTX PRO line using the rumored GR202 die. The DL585a Gen13 is a 10U system with two AMD EPYC 9006 processors, support for eight dual-width or 16 single-width expansion cards, and 16 EDSFF E3.S (Thin) drive bays.
