In AI infrastructure, the network has evolved from a supporting role to center stage. As AI clusters demand unprecedented bandwidth and razor-sharp latency, traditional networking approaches are breaking down. Broadcom’s response? Three specialized Ethernet switch chips—each designed to solve specific pieces of the AI networking puzzle.

At a recent AI Infrastructure Field Day event, Broadcom executives provided in-depth technical briefings on these new chips, showcasing how their features directly address the complex demands of modern AI infrastructure. They emphasized a full-stack approach, providing not just the switch silicon but also network interface cards (NICs), NIC chiplets for custom XPU integration, physical layer products like retimers and optics, and a framework for using Ethernet efficiently for scale-up.
