AMD's TH6 switch design relies on Broadcom for key components

By PulseAugur Editorial · [1 sources] ·

AMD has publicly revealed its TH6 scale-up switch design, a crucial component for building large-scale AI systems. However, the design relies on Broadcom for essential ethernet retimers and scale-up switches, indicating a gap in AMD's own silicon product portfolio for such systems. AMD is also collaborating with UALink switch vendors to develop a complete UALink scale-up system. AI

IMPACT Highlights the reliance on third-party components for large-scale AI infrastructure, potentially impacting supply chain and performance.

RANK_REASON The item discusses a specific hardware design (TH6 scale up switch) and its reliance on third-party components (Broadcom ethernet retimers), which falls under hardware tooling rather than a core AI release or significant industry shift.
