Broadcom has announced the shipment of its Tomahawk 6 (BCM78910) switch chip series, the first Ethernet switches to deliver 102.4 Tbps switching capacity. This represents double the performance of any Ethernet switches currently available in the market today.
Incredible Scaling Capabilities
The innovation is specifically optimized for large AI clusters and offers impressive scaling possibilities:
- Scale-up configuration: Connect up to 512 XPUs in a single cluster
- Scale-out configuration: Over 100,000 XPUs at 200GbE per connection
- Maximum configuration: Up to 1 million XPUs within a single solution
Advanced Connectivity Technologies
Tomahawk 6 features 100G/200G PAM SerDes blocks supporting long-reach passive copper connections. A variant with integrated optical interfaces (CPO) is also available, providing:
- Enhanced energy efficiency
- Lower latency levels
- Increased operational stability
Intelligent Routing with Cognitive Routing 2.0
Built-in Cognitive Routing 2.0 technology automatically detects congestion and redirects data flows through alternative routes. The system includes:
- Advanced telemetry
- Dynamic congestion control
- Fast failure detection
- Global load balancing
Flexible Port Configurations
Tomahawk 6 supports multiple port configurations:
- 64 × 1.6TbE
- 128 × 800GbE
- 256 × 400GbE
- 512 × 200GbE
- 1024 × 100GbE
"Tomahawk 6 is not just an upgrade, it's a breakthrough," stated Ram Velaga, Senior Vice President at Broadcom. "It marks a turning point in AI infrastructure design."
