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. 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. With extreme co-design, Nvidia takes rack scale integration to the next level.

Evidence

Rack system becomes a unit of compute, a single distributed accelerator

Context After

, and Nvidia designs the system.

② Atomic Claim

關於 Rubin：Rack system 被視為一個 compute unit，也就是單一 distributed accelerator。
