Improved AI Cloud Performance
NVIDIA Spectrum-X Ethernet enhances network performance by 1.6x, accelerating the processing, analysis, and execution of AI workloads and, in turn, the development and deployment of AI solutions.
Accelerated Ethernet for Hyperscale
Powered by NVIDIA networking innovations, Spectrum-X Ethernet is fully standards-based Ethernet with support for open Ethernet stacks (SONiC) at cloud scale.
Full-Stack Optimization
Spectrum-X Ethernet is tuned and validated across the full stack of NVIDIA hardware and software, creating an unmatched Ethernet solution for AI clouds.
Connect Data Centers for Giga-Scale AI
NVIDIA Spectrum-XGS Ethernet is built for scaling across multiple disparate data centers—located in different buildings or separated by hundreds of kilometers—allowing them to function as a single unified AI super-factory. Spectrum-XGS Ethernet uses a topology-aware congestion control algorithm, precise latency management, and end-to-end telemetry to deliver 1.9x higher NCCL performance in cross-data center environments.
Products
What’s Inside the Platform
NVIDIA Spectrum-X Ethernet Switches
The NVIDIA Spectrum Ethernet SN5000 series switches are the fifth generation of Spectrum Ethernet switches, purpose-built to accelerate hyperscale generative AI fabrics. With port speeds reaching up to 800 gigabits per second (Gb/s), SN5000 switches deliver accelerated Ethernet for every data center without compromising between performance and features.
NVIDIA Spectrum-X Ethernet SuperNICs
The NVIDIA Spectrum-X Ethernet SuperNICs, are novel classes of network accelerators, purpose-built for supercharging hyperscale AI workloads. Designed for network-intensive, massively parallel computations, NVIDIA SuperNICs provide up to 800 Gb/s of RDMA over Converged Ethernet (RoCE) network connectivity between GPU servers, optimizing peak AI workload efficiency.
