- Broadcom launches Tomahawk 6 series, a 102.4Tbps switch supporting up to 64 ports of 1.6TbE.
- Two ASIC models available: BCM78910 and BCM78914, catering to different configurations and applications.
- Features include co-packaged optics, 512x 200G PAM4 or 1024x 100G PAM4 options, and Global Load Balancing 2.0.
- Cognitive Routing 2.0 enhances load balancing across network paths, improving data movement efficiency.
- Designed for both scale-up (high bandwidth between fewer nodes) and scale-out (connecting numerous accelerators).
- Advantages include reduced latency, fewer switches, lower power consumption, and cost savings on optics and cables.
- Tomahawk 6 addresses the growing demand in AI clusters, where networking is a significant cost and power consumer.
- Broadcom faces competition from NVIDIA, which is closing its ecosystem to non-NVIDIA NICs and PCIe switches.
- Power and noise make these switches impractical for home labs, with most ending up in collections or museums.
- The market is bifurcating, with high-end AI switches receiving more investment than low-power alternatives.
