NVIDIA's new 102.4-terabit-per-second Spectrum-6 Ethernet switch, part of the Vera Rubin platform, doubles previous generation capacity for AI factories. Leading AI infrastructure builders including CoreWeave, Microsoft, Nebius, SpaceXAI, and Tesla will be among the first to deploy Spectrum-6. The system supports both pluggable and co-packaged optics, and liquid cooling, enhancing network power efficiency and AI networking performance by up to 1.6x.
NVIDIA's new Ethernet switch solidifies its full-stack AI infrastructure dominance, forcing hyperscalers to adopt its proprietary networking for optimal GPU utilization.
