NVIDIA Spectrum-X Sets Gigascale AI Ethernet Standard with Multi-Rail Connectivity — Open, AI-Native Fabric
NVIDIA announced Spectrum-X Ethernet scale-out infrastructure with Multi-Rail Connectivity (MRC) designed for gigascale AI factory networking. The announcement positions Spectrum-X as the open, AI-native alternative to proprietary fabrics, directly addressing the networking bottleneck as AI clusters grow beyond single-rack scale. This is infrastructure plumbing for the data center buildout that Anthropic, OpenAI, and others are racing to construct.
