On March 20th, the AI new era demands increasingly higher computational power and models, as well as stronger networks. To address this, NVIDIA released a new network switch, the X800 series, specifically designed for large-scale AI.
It is reported that NVIDIA’s Quantum-X800 InfiniBand network and Spectrum-X800 Ethernet network are the world’s first network platforms with up to 800Gbps end-to-end throughput. Early users include Microsoft Azure, Oracle Cloud, Coreweave, and others.
The Quantum-X800 platform is considered a new benchmark for the ultimate performance of AI-specific infrastructure, featuring the Quantum Q3400 switch and ConnectX-8 SuperNIC network card. The interconnected end-to-end throughput reaches an industry-leading 800Gbps (800,000 Gbps).
Additionally, the switch bandwidth capacity is five times higher than the previous generation, and the network computing power has increased nine times thanks to NVIDIA’s SHARPv4 technology, reaching 14.4TFlops, or 14.4 trillion calculations per second.
The Spectrum-X800 includes the Spectrum SN5600 switch and BlueField-3 SuperNIC network card, also with a throughput of up to 800Gbps, providing various advanced features essential for multi-tenant AIGC clouds and large enterprise users.
On the software side, NVIDIA provides a complete set of software solutions for network acceleration communication libraries, software development kits, and management software, all aimed at optimizing the performance of AI models with trillions of parameters.
Among them, NVIDIA’s Collective Communication Library (NCCL) can extend the GPU’s parallel computing tasks to the Quantum-X800 network and utilize the powerful network computing capabilities based on SHARPv4 and support for the FP8 data format, offering exceptional performance for large model training and AIGC.
Starting from 2025, numerous leading infrastructure providers and system manufacturers worldwide will offer network platforms based on Quantum-X800 and Spectrum-X800, including Aivres, DDN, Dell, Eviden, Hitachi Vantara, Inspur, Lenovo, Supermicro, VAST Data, and others.
