NVIDIA says its Spectrum-6 Ethernet switch system is arriving at gigascale AI factories built around the Vera Rubin platform. The system delivers 102.4 Tbps of switching capacity, described as twice that of previous-generation systems, and anchors the next generation of NVIDIA’s Spectrum-X Ethernet platform. The company positions it as infrastructure for clusters combining hundreds of thousands of GPUs and CPUs to train frontier models, run agentic AI, and serve inference workloads. CoreWeave, Microsoft, Nebius, SpaceXAI, and Tesla are named as early adopters. The announcement is NVIDIA’s account; independent performance data is not included in the supplied material.
