NVIDIA Unveils the Next-Generation Rubin Platform
At CES 2026, NVIDIA introduced the next-generation NVIDIA Rubin platform, which consists of six new chips specifically designed to build extraordinary AI supercomputers. NVIDIA Rubin sets a new benchmark by enabling the construction, deployment, and secure operation of the largest and most advanced AI systems at the lowest cost, thereby accelerating the adoption of mainstream AI.
The NVIDIA Rubin platform is meticulously co-designed with six components—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 significantly reduce training time and lower inference token costs. NVIDIA Rubin is now fully in mass production, and Rubin-based products will be available through partners in the second half of 2026.
In the field of optics, NVIDIA Spectrum-X Ethernet silicon photonics switching system can improve energy efficiency and operational duration by fivefold. NVIDIA CEO Jensen Huang stated that the Spectrum-6 Ethernet switching chip features 352 billion transistors, employs 200G silicon photonics and CPO packaging technologies, and supports either 512 ports at 200Gb/s or 128 ports at 800Gb/s, enabling AI cluster Scale-Out expansion with a switching capacity of 102.4Tb/s.
New Generation Ethernet Network
Advanced Ethernet networks and storage are crucial components of AI infrastructure, essential for ensuring the full-speed operation of data centers, improving performance and efficiency, and reducing costs.
NVIDIA Spectrum-6 Ethernet is a new-generation Ethernet designed for AI networks, aimed at expanding Rubin-based AI factories with higher efficiency and reliability. It supports 200G SerDes, co-packaged optics (CPO), and AI-optimized networking technologies.
Built on the Spectrum-6 architecture, the Spectrum-X integrated optical-electrical Ethernet silicon photonic switch system delivers 10 times the reliability and 5 times the sustained uptime for AI applications, while achieving a 5-fold improvement in energy efficiency. Compared to traditional technologies, it maximizes performance per watt. As part of the Spectrum-X Ethernet platform, Spectrum-XGS Ethernet technology connects multiple infrastructures spanning hundreds of kilometers or more, enabling operation as a single unified AI environment.
These innovations collectively define the new-generation NVIDIA Spectrum-X Ethernet platform, enabling Rubin to achieve unparalleled engineering collaboration for driving large-scale AI factories and paving the way for future million-GPU environments.
