NVIDIA Spectrum-X

What is NVIDIA Spectrum-X

NVIDIA Spectrum-X is the world's first high-performance Ethernet networking platform specifically designed for artificial intelligence (AI)-based solutions. It combines the NVIDIA Spectrum-4 Ethernet switch and NVIDIA BlueField-3 intelligent network cards (DPUs) to create a scalable, fast, and energy-efficient network optimized for AI computing workloads. The platform enables large data centers to build AI clouds with the high performance and predictable stability critical to current and future generative models and distributed computing.

Key features and capabilities of NVIDIA Spectrum-X:

• High bandwidth: Spectrum-4 switch delivers up to 51 Tbps with support for up to 128 ports at 400 Gbps or 64 ports at 800 Gbps.
• BlueField-3 DPU integration: BlueField-3 is responsible for optimizing data transfer and network traffic management by supporting GPUDirect RDMA, which improves overall network performance over traditional Ethernet by approximately 1.6 to 1.7 times.
• Optimization for AI workloads: The platform supports large-scale distributed AI computing such as generative model training and inference (GPT, BERT), natural language processing (NLP), computer vision, high-performance simulation (NVIDIA Omniverse and OVX), and data analytics.
• AI-Driven Networking: Spectrum-X uses machine learning to intelligently manage traffic, reallocate resources, diagnose faults, and predictive maintenance to reduce latency, increase network throughput by up to 40 percent, and reduce downtime by approximately 25 percent.
• Compatibility and Standards: The platform is based on open Ethernet standards, supports the SONiC stack, and integrates with the NVIDIA software ecosystem, including DOCA tools, NetQ, and Linux distributions (Cumulus, Pure SONiC).
• Applications: The platform is suitable for scalable AI clouds, hyperscale environments, data centers with compute-intensive AI tasks and low latency requirements.
