Ethernet platform purpose-built for AI, from single-cluster fabrics to multi-site AI factories with Spectrum-XGS.
NVIDIA Spectrum-X is an end-to-end Ethernet platform built for multi-tenant generative AI factories. Spectrum-X switches and SuperNICs work together to deliver the bandwidth, low latency and performance isolation that AI needs on standards-based Ethernet.
Spectrum-XGS extends the same fabric across data centers, so geographically distributed sites can operate as one large AI factory.
Compared with off-the-shelf Ethernet for AI workloads.
Two-tier topologies reach hundreds of thousands of GPUs; Multiplane extends to 128,000 GPUs.
Telemetry-based congestion control keeps noisy neighbours from slowing other jobs.
Switch and SuperNIC coordinate to maximise effective bandwidth and resilience.
Multi-site NCCL collectives run up to 1.9x faster across data centers.
Up to 5x better power efficiency than transceiver-based networks.
