AI networking startups race to replace Nvidia's NVLink

At AI Infra Summit, Cornelis Networks and Delos Data presented alternatives to Nvidia's proprietary NVLink interconnect. Cornelis announced the open Active Compute Fabric architecture, while Delos showed I/O chiplets with over 30 Tbps throughput, twice that of Nvidia and AMD.

• Cornelis unveiled open ACF architecture for scale-up and scale-out networks
• Delos Data showed I/O chiplets with over 30 Tbps throughput
• Nvidia and AMD interconnects are limited to 3.6 TB/s
• Cornelis estimates half of time is idle in a 100,000-GPU system
