About the Broadcom BCM87800 Tomahawk 5 Ethernet Switch ASIC
The Broadcom BCM87800 Tomahawk 5 Ethernet Switch ASIC delivers industry-leading port density with support for 512 × 100GbE, 256 × 200GbE, 128 × 400GbE, or 64 × 800GbE configurations, enabling hyperscale datacenter operators to maximize throughput on every fabric. Built as a single-chip ASIC optimized for OEM integration, this Broadcom component achieves a total switching bandwidth of 51.2 Tbps and a forwarding capacity of 38.4 Bpps, making it the ideal foundation for next-generation spine and leaf architectures, AI/ML fabric deployments, and DDC line cards.
Network engineers and AI infrastructure teams rely on the BCM87800 for its non-blocking shared-memory switching architecture, which eliminates packet loss under heavy loads while maintaining deterministic performance. Advanced congestion control mechanisms—including PFC, ECN, and DCQCN—work alongside in-band network telemetry and per-flow statistics to provide unprecedented visibility into network behavior. The chip's 112 Gbps PAM4 per-lane SerDes speed ensures maximum efficiency across all port configurations, while flexible load balancing via ECMP and weighted ECMP distributes traffic intelligently. Multiple NOS environments are supported, including SONiC, Broadcom NOS, and open NOS via the Network SDK, delivering deployment flexibility for operators of all scales.
