AI Data Center Networking: Scaling Up, Out, and Across with 102.4T Ethernet
As AI clusters scale, network silicon becomes the bottleneck. Here’s a look at Cisco’s Silicon One G300 and P200, alongside Broadcom’s Tomahawk 6 and Nvidia’s Spectrum-6.

As AI clusters grow larger with thousands of GPUs, the network connecting them has become a critical bottleneck that can determine overall efficiency. High-speed Ethernet switching silicon at 51.2 to 102.4 Tbps capacity, produced by multiple vendors, is designed to deliver predictable bandwidth and low latency while managing sudden traffic bursts. Without adequate network infrastructure, expensive GPU investments become underutilized hardware rather than functional supercomputers. These advanced networking chips employ deeper buffering, real-time telemetry, and load-balancing strategies to keep data flowing smoothly within and between data centers.
