NVIDIA Spectrum-6 Arrives in Gigascale AI Factories | NVIDIA Blog
NVIDIA has introduced Spectrum-6, a 102.4-terabit-per-second Ethernet switch system designed for gigascale AI factories as part of the Vera Rubin platform.
Why it matters
By reducing network bottlenecks, this technology allows cloud providers to train larger AI models faster and more efficiently, potentially lowering the cost of generating AI outputs.
The details
- Spectrum-6 delivers 2x the capacity of previous-generation Ethernet switch systems.
- Early adopters include Microsoft, CoreWeave, Nebius, SpaceXAI and Tesla.
- The system supports liquid cooling to increase power efficiency in AI factories.
