Lisa Su was in Seoul this week meeting with SK hynix and Samsung on HBM4 supply. $AMD is already ramping MI455X systems with HBM4, which carry 432 GB of memory per GPU. Su called the memory environment "very tight," said AMD is planning supply three to five years out, and told reporters in Taipei the company will "substantially increase" supply in 2027. Memory is the constraint on AI compute right now. The companies that secure allocation are the ones that book the revenue. AMD is up 524.98% since I first brought it to the OBA family's attention, and I think it's still got a ways to go. Buy the Best, Ignore the Rest.®
