Nvidia has unveiled Rubin, its next-generation GPU architecture and tightly integrated AI computing platform that is set to replace its current flagship Blackwell architecture. Rubin is Nvidia’s first extreme-co-designed platform and will comprise six AI chips, alongside various networking technologies and system software, all working together as a single computing unit. It was launched by Nvidia founder and CEO Jensen Huang onstage at CES 2026. Rubin computing units are already in full production, and are expected to launch in the second half of 2026.
“Rubin arrives at exactly the right moment, as AI computing demand for both training and inference is going through the roof,” said Jensen Huang, founder and CEO of NVIDIA. “With our annual cadence of delivering a new generation of AI supercomputers — and extreme codesign across six new chips — Rubin takes a giant leap toward the next frontier of AI.”
Named for Vera Florence Cooper Rubin, the trailblazing American astronomer whose discoveries transformed humanity’s understanding of the universe, the Rubin platform features the NVIDIA Vera Rubin NVL72 rack-scale solution and the NVIDIA HGX Rubin NVL8 system.
The Rubin platform introduces five innovations, including the latest generations of NVIDIA NVLink interconnect technology, Transformer Engine, Confidential Computing and RAS Engine, as well as the NVIDIA Vera CPU. These breakthroughs will accelerate agentic AI, advanced reasoning and massive-scale mixture-of-experts (MoE) model inference at up to 10x lower cost per token of the NVIDIA Blackwell platform. Compared with its predecessor, the NVIDIA Rubin platform trains MoE models with 4x fewer GPUs to accelerate AI adoption.
The Rubin platform uses extreme codesign across the six chips — the NVIDIA Vera CPU, NVIDIA Rubin GPU, NVIDIA NVLink 6 Switch, NVIDIA ConnectX-9 SuperNIC, NVIDIA BlueField-4 DPU and NVIDIA Spectrum-6 Ethernet Switch — to slash training time and inference token costs.
