Nvidia’s CPO Roadmap
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. 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.
