Scaling Power-Efficient AI Factories with NVIDIA Spectrum-X Ethernet Photonics | NVIDIA Technical Blog

NVIDIA is quietly reshaping the economics of artificial intelligence by replacing the copper wiring that connects its most powerful chips with fiber-optic cables, a shift that could slash the energy costs of training giant AI models by tens of millions of dollars annually. The move, announced through its new Spectrum-X Ethernet system, suggests that the real bottleneck in AI development is no longer raw computing power but the staggering electricity bills required to wire data centers together. If the technology proves as efficient as promised, it could determine which companies can afford to build the next generation of AI systems—and which cannot.
