NVIDIA’s Vera Rubin racks feature an unprecedented amount of memory, and that comes with a hefty price tag, as disclosed in the “Bill of Materials”.
Memory Accounted For 53% in Grace Blackwell Servers, but Vera Rubin Pushes That To 62% With Double The Price Bump
Vera Rubin racks are crazy expensive, and while one would expect to pay a premium for these next-generation enterprise powerhouses, the main cost driver is, unsurprisingly, the memory & that accounts for 62% of the cost of the Vera Rubin platform alone.
While we have covered the NVIDIA Vera Rubin rack costs and BOM in the past few months, the latest one shared by UBS dissects the cost of each Vera Rubin Superchip and the respective rack that these are configured in. The Vera Rubin NVL72 server, codenamed Oberon, features 72 GPUs based on the Rubin architecture, and massive amounts of memory.
The chip alone features 288 GB of HBM4 memory, delivering up to 22 TB/s bandwidth, while the Vera CPU is attached to the latest SOCAMM2 LPDDR5X solution, carrying up to 1.5 TB of memory per Superchip.
The Superchip & NVL72 Basics
Let’s start with the basics: the NVIDIA NVL72 rack is called Oberon and makes use of 72 GPUs plus 36 CPUs. A single Vera Rubin tray houses 4 “Rubin” GPUs and 2 “Vera” CPUs. Two GPUs and a single CPU are housed on a motherboard, which is called a Superchip. There are 36 Superchips on the NVL 72 rack. So that’s a total of 72 GPUs and 36 CPUs.
