Flexible Connectivity Options with Co-Packaged Optics Support
The innovations of Tomahawk 6 extend far beyond the chip, delivering full system-level power efficiency and cost savings, enabled by Broadcom’s best-in-class SerDes and optics ecosystem. With industry-leading 200G SerDes, it provides the longest reach for passive copper interconnect, enabling high-efficiency, low-latency system design with the highest reliability and lowest total cost of ownership (TCO). The Tomahawk 6 family includes a groundbreaking option for 1,024 100G SerDes on a single chip, enabling customers to deploy AI clusters with extended copper reach and efficient use of XPUs and optics with native 100G interfaces.
For systems requiring optical connectivity, Tomahawk 6 will also be available with co-packaged optics, providing the lowest power and latency while reducing link flaps and improving long-term reliability – essential advantages for hyperscale AI network operators. The Tomahawk 6 CPO solution builds upon the technology Broadcom delivered with CPO versions of Tomahawk 4 and 5.
AI-Optimized Routing for Scale-Up and 1M+ XPU Scale-Out Networks
Tomahawk 6’s architecture enables unified networks for AI training and inference at unprecedented scale. Cognitive Routing 2.0 in Tomahawk 6 features advanced telemetry, dynamic congestion control, rapid failure detection, and packet trimming, enabling global load balancing and adaptive flow control. These capabilities are tailored for modern AI workloads, including mixture-of-experts, fine-tuning, reinforcement learning, and reasoning models.
With scale-out and scale-up networking support, Tomahawk 6 meets all networking demands for emerging 100,000 to one million XPU clusters. Leveraging Ethernet for both scale-out and scale-up interfaces offers significant advantages for network operators, enabling them to use a unified technology stack and consistent operational tools across the entire AI fabric. It also enables fungible interfaces where cloud operators can dynamically partition their XPU assets into the optimal configuration for different customer workloads.
The momentum behind Tomahawk 6 and Ethernet for all backend networking needs is unmistakable. Multiple deployments are planned with more than 100,000 XPUs using Tomahawk 6 for both the scale-out and scale-up interconnect.
