SK Hynix's HBM4 yield has reportedly surpassed 70%, a level that could lift output by roughly 16.7% at equal production input versus 60%, seen as the key variable for mass-production competitiveness in next-gen high-bandwidth memory. Samsung is said to be near 80% and Micron is pushing hard, with early HBM4 yield and stable supply expected to shape future market share.
