HBM4 Demand Holds Firm As Rubin Keeps 12 Layers

Counterpoint Research reports that Nvidia's Rubin AI accelerator will use 12-layer HBM4, dispelling concerns of reduced memory demand. Samsung Electronics and SK hynix are expected to benefit from growing HBM4 demand. Samsung's Q3 revenue and operating profit surged 126.6% and 782.5% YoY, respectively, to 195 trillion won and 107.4 trillion won. Counterpoint attributes the strong performance to high-value memory demand, though exchange rates tempered earnings growth.
