NextFin news, On August 22, 2025, NVIDIA, the American technology company, introduced Spectrum-XGS Ethernet, a new scale-across networking technology designed to connect multiple distributed data centers into unified giga-scale AI super-factories. The announcement was made in the United States and detailed at the Hot Chips conference held at Stanford University.
The Spectrum-XGS Ethernet technology extends NVIDIA's existing Spectrum-X Ethernet platform by enabling data centers located across cities, nations, and continents to interconnect with ultra-low latency, precision latency management, and dynamic congestion control. This innovation addresses the physical and power capacity limitations faced by individual data centers, which are reaching their maximum scale within single facilities.
Jensen Huang, founder and CEO of NVIDIA, stated that the technology adds a third pillar of AI computing—scale-across—beyond the traditional scale-up and scale-out methods, allowing the formation of massive AI super-factories capable of giga-scale intelligence.
The technology integrates advanced algorithms that dynamically adapt network performance based on the distance between data centers, nearly doubling the performance of NVIDIA's Collective Communications Library (NCCL), which accelerates multi-GPU and multi-node communication for distributed AI workloads.
CoreWeave, a hyperscale cloud infrastructure provider, is among the first to deploy Spectrum-XGS Ethernet, aiming to connect its data centers into a single unified supercomputer to provide customers with access to giga-scale AI capabilities.
The Spectrum-X Ethernet platform, including Spectrum-XGS, offers 1.6 times greater bandwidth density than standard Ethernet solutions and incorporates NVIDIA Spectrum-X switches and ConnectX-8 SuperNICs to deliver scalable, ultra-low latency networking optimized for AI workloads.
This announcement follows NVIDIA's recent innovations in networking, including the Spectrum-X and Quantum-X silicon photonics switches, which facilitate the connection of millions of GPUs across multiple sites while reducing energy consumption and operational costs.
Spectrum-XGS Ethernet is currently available as part of the NVIDIA Spectrum-X Ethernet platform.
