NVIDIA will construct one of the world’s fastest supercomputers, the NVIDIA Spectrum-X, an accelerated networking platform the company said is designed to improve the performance and efficiency of Ethernet-based AI clouds. To that end, the company developed, over the past 18 months, the Israel-1 supercomputer in its Israeli data center which will be used in support of the new program. Jensen Huang, founder and CEO of Nvidia, announced the new plans while speaking in Taiwan.
The Israel-1 is a hyperscale generative AI supercomputer to be deployed in NVIDIA’s Israeli data center on Dell PowerEdge XE9680 servers based on the NVIDIA HGX™ H100 eight-GPU platform, BlueField-3 DPUs and Spectrum-4 switches.
NVIDIA said the Spectrum-X is built on networking innovations powered by the tight coupling of the NVIDIA Spectrum-4 Ethernet switch with the NVIDIA BlueField-3 DPU, achieving 1.7x better overall AI performance and power efficiency, along with consistent, predictable performance in multi-tenant environments. Spectrum-X is supercharged by NVIDIA acceleration software and software development kits (SDKs), allowing developers to build software-defined, cloud-native AI applications.

The NVIDIA Spectrum-X networking platform is highly versatile and can be used in various AI applications. It uses fully standards-based Ethernet and is interoperable with Ethernet-based stacks.
The platform starts with Spectrum-4, the world’s first 51Tb/sec Ethernet switch built specifically for AI networks. Advanced RoCE extensions work in concert across the Spectrum-4 switches, BlueField-3 DPUs and NVIDIA LinkX optics to create an end-to-end 400GbE network that is optimized for AI clouds.
Gilad Shainer, senior vice president of networking at Nvidia, said, “Transformative technologies such as generative AI are forcing every enterprise to push the boundaries of data center performance in pursuit of competitive advantage. Nvidia Spectrum-X is a new class of Ethernet networking that removes barriers for next-generation AI workloads that have the potential to transform entire industries.”
NVIDIA Spectrum-X enables unprecedented scale of 256 200Gb/s ports connected by a single switch, or 16,000 ports in a two-tier leaf-spine topology to support the growth and expansion of AI clouds while maintaining high levels of performance and minimizing network latency.
