AMD CEO Says HBM4 Push Backed by Samsung and SK Hynix

The signal here is less about AMD's own roadmap than about the supply chain behind it: naming both Korean memory makers suggests HBM4 capacity and qualification are being lined up well ahead of systems shipping, which is the part of AI hardware that has historically gated launches. That matters for anyone tracking where advanced memory supply gets allocated and how much leverage the two suppliers hold. Whether that support translates into volume availability, rather than just stated backing, is the open question.
