ChipsThe story, in brief
Built for Vera Rubin, NVIDIA Spectrum-6 Arrives in Gigascale AI Factories
Networking just became the bottleneck. NVIDIA's Spectrum-6 is built for the 500k+ GPU datacenters that are coming.
The KeyNews take
Why it matters
As AI factories scale to hundreds of thousands of GPUs, networking infrastructure—not compute—is becoming the critical constraint for token throughput. Spectrum-6 is NVIDIA's answer to keeping gigascale clusters from choking on their own bandwidth.
