Transcript
NVIDIA just shipped Spectrum-6, a 102.4 terabit Ethernet switch built for gigascale AI factories.
NVIDIA's new Spectrum-6 switch delivers twice the networking capacity of the previous generation, built as the core of the Vera Rubin platform.
The first adopters include CoreWeave, Microsoft, Nebius, SpaceXAI, and Tesla, all deploying Spectrum-6 in their AI factories.
Spectrum-X Ethernet delivers 1.6 times higher networking performance than standard Ethernet, with 95 percent efficiency across more than 100,000 GPUs.
Spectrum-6 multiplane topologies cut required switches by 1.7 times. AI factories can now operate as one unified computing system.
