Ethernet networking platform purpose-built for generative AI clouds with predictable performance and congestion control.
Spectrum-X is NVIDIA's Ethernet networking platform for generative AI data centers. The platform pairs Spectrum-4 Ethernet switches with BlueField-3 SuperNICs and dynamic routing software to deliver predictable, low-jitter performance for east-west AI traffic.
Spectrum-X supports adaptive routing, RoCE-based congestion control, and telemetry-driven performance isolation across multi-tenant AI clouds. Hyperscale operators, AI cloud builders, and large enterprises deploy Spectrum-X alongside NVIDIA Quantum InfiniBand and BlueField DPUs in NVIDIA's AI factory reference architectures.
