Context Before

NVIDIA revealed its CPO Roadmap at the GTC Keynote 2026, with Jensen following up with additional commentary in the Financial Analyst Q+A meeting held the following day.

Evidence

Though many had their hopes up for CPO to be used for scale-up within the rack for Rubin Ultra Kyber, Nvidia’s focus was instead on using CPO to enable larger world size compute systems.

Context After

In the Rubin Generation, Nvidia will offer the Rubin GPU in an Oberon NVL72 form factor with an all-copper scale-up network. For Rubin Ultra, as we expected, there will only be a copper scale-up option for Rubin Ultra in the Oberon and Kyber Rack form factor. Rubin Ultra will also be offered in a larger world size system that connects 8 Oberon Racks of 72 Rubin Ultra GPUs to form what will be referred to as NVL576.

② Atomic Claim

雖然市場原本期待 CPO 用於 Rubin Ultra Kyber rack 內的 scale-up，Nvidia 的重點反而是用 CPO 支援更大的 world-size compute system。
