Built for Vera Rubin, NVIDIA Spectrum-6 Arrives in Gigascale AI Factories
NVIDIA Scot Schultz ● Covered by 7 sources
NVIDIA released Spectrum-6, a 102.4-terabit-per-second Ethernet switch system that doubles the capacity of previous-generation switches, designed to connect hundreds of thousands of GPUs in large AI training facilities. CoreWeave, Microsoft, Nebius, SpaceX AI and Tesla are among the first to deploy Spectrum-6 as part of NVIDIA's Vera Rubin platform. The switch enables better coordination between GPUs during large-scale training and inference, reducing bottlenecks that occur when GPUs need to exchange data continuously at gigascale.
Why it matters
AI has entered the gigascale era. The world’s most advanced AI factories are bringing together hundreds of thousands of GPUs and CPUs to train frontier models, power agentic AI and generate intelligence at unprecedented scale. At this level, networking becomes a critical computing power multiplier in driving token generation. Marking a networking milestone, NVIDIA Spectrum-6 […]
