At GTC, Nvidia introduced the Spectrum-X and Quantum-X switches designed to support AI data centers featuring millions of GPUs. By employing silicon photonics and co-packaged optics, these new products promise significant reductions in energy consumption and operational costs. The Quantum-X will offer 144 ports of 800 Gbps InfiniBand, while the Spectrum-X is expected in 2026 with configurations providing up to 100 Tbps total bandwidth. These innovations aim to address bandwidth bottlenecks and enhance AI computing scalability, leading to more efficient data center operations.
Nvidia's new Spectrum-X and Quantum-X switches utilize silicon photonics to reduce energy consumption while enabling millions of GPUs for advanced AI factory setups.
The co-packaged optics concept allows for greater efficiency, with decreased power usage and latency achieved by integrating optical and silicon components in a single package.
