Context Before

At CES 2026, Nvidia officially announced in detail all 6 Rubin platform products: the Rubin GPU, Vera CPU, NVLink 6 Switch, ConnectX-9, BlueField-4, and Spectrum-6. VR NVL72 is the second generation of Nvidia’s rack scale Oberon architecture that takes the stage.

Evidence

With competition catching up on rack scale game, Trainium 3 in the Gen2 UltraServer, AMD MI450X Helios Racks, and Google’s TPU which was at rack scale even before GB200, Nvidia answers with “extreme co-design” supremacy.

Context After

With extreme co-design, Nvidia takes rack scale integration to the next level. Rack system becomes a unit of compute, a single distributed accelerator, and Nvidia designs the system.

② Atomic Claim

隨著 rack-scale 競爭者追近，包括 Gen2 UltraServer 的 Trainium 3、AMD MI450X Helios rack，以及早於 GB200 就達到 rack scale 的 Google TPU，Nvidia 以「extreme co-design」作為回應。
