Nvidia CEO Jensen Huang officially announced the Spectrum-X and Quantum-X silicon photonic (SiPh) network switches, enabling AI factories to connect millions of GPUs across different locations while significantly reducing energy consumption and operational costs.

“AI factories are a new class of data centers with extreme scale, and networking infrastructure must be reinvented to keep pace,” Huang said. “By integrating silicon photonics directly into switches, Nvidia is shattering the old limitations of hyperscale and enterprise networks and opening the gate to million-GPU AI factories.”
