Nvidia launches Spectrum-6 switches for AI data center networking

Nvidia debuted its Spectrum-6 switch line aimed at next-generation AI networking. Microsoft and SpaceX/xAI are named among the early users of the new hardware.

Why it matters: Networking is increasingly a bottleneck in scaling AI training clusters, not just raw compute. A new switch generation adopted early by hyperscalers like Microsoft and xAI signals where the next round of AI infrastructure investment is headed, alongside Nvidia's GPU and CPU roadmap.
