Nvidia Rubin Ultra HBM Spec Downgrade Under Review as HBM4/4E Supply Crunch Deepens Through 2027
TrendForce reports Nvidia is actively evaluating downgraded HBM configurations for its Rubin Ultra AI accelerator platform — substituting the baseline 12-high HBM4E stack with 8-high HBM4E, 12-high HBM4, or 8-high HBM4 alternatives — due to a worsening DRAM supply shortage and yield/qualification uncertainty on 12-high HBM4E modules. Concurrently, Micron confirms its entire 2026 HBM4 production is sold out with customers receiving only 60–70% of ordered volumes, and TrendForce flags the supply deficit extending through 2027, cementing pricing power firmly with Samsung and SK Hynix.
