Key Points
Spec: up to 20-core Grace ARM CPU plus Blackwell GPU (6,144 CUDA cores), 128GB LPDDR5X, 300 GB/s bandwidth
Performance: 1 petaflop of AI compute in a portable form factor
Fab: TSMC 3nm; OEMs include Microsoft Surface Laptop Ultra, Dell, HP, ASUS, Lenovo, MSI
Roadmap announced through 2030: Vera Rubin (LPDDR6) then Rosa Feynman generations
Vera CPU now in full production with OpenAI, Anthropic, and SpaceX named as early adopters
Why It Matters
Nvidia is no longer just the data-center GPU vendor — it is the CPU vendor too, and Intel and AMD now have to defend the AI PC tier from a competitor that already owns the model layer.
