Oberon and Kyber Updates, Larger World Sizes Introduced, More Networking Updates
Evidence
Nvidia provided a long-awaited update on its Kyber rack form factor, the latest addition to the lineup after Oberon having first been previewed as a prototype at GTC 2025. As a prototype, the rack architecture has continued to evolve, and we notice some changes. First, each compute blade has densified, with 4x Rubin Ultra GPU and 2x Vera each. There are a total of 2 canisters of 18 compute blades which amounts to 36 compute blades total for 144 GPUs in a rack. The initial Kyber design featured 2 GPUs and 2 Vera CPUs in one compute blade, with a total of 4 canisters of 18 compute blades each.
Context After
The details below are based on the Rubin Kyber prototypes, but Rubin Ultra will be redone.
