The open scale-up standard: everyone-but-NVIDIA's answer to NVLink.
You're looking at a technology record: a building block of AI hardware — what it does, who makes it, and which chips and systems use it.
UALink 1.0 (April 2025) defines a 200 Gb/s-per-lane, memory-semantic fabric connecting up to 1,024 accelerators in one pod — the standard AMD's Helios racks adopt and Apple, AWS, Google, Intel, Meta and Microsoft back. Its success or failure decides whether rack-scale computing stays proprietary.
