Astera Labs is no longer just a retimer company. Q1 results show its Scorpio switch family is set to become the main revenue driver, with content per system rising sharply. As custom CXL demand emerges, ALAB is reshaping how AI clusters are connected.

AMD's OCP keynote was framed around open standards, but the line worth underlining is the CPU-to-GPU ratio converging from 1:4 toward 1:1. Agentic workflows hand orchestration, retrieval and tool execution back to the CPU — and that matters far more to Taiwan's rack-integration and scale-up optical interconnect supply chain than a slide full of open acronyms.

The keynote looked like a GPU show, but the real story is that AMD bet the Helios rack backbone on open Ethernet and wrote optical interconnect into the MI500 spec. That favors merchant optics, DSPs, and lasers — but order timing splits into near-term scale-out and longer-term scale-up.
