HBM Design Architecture Fellow Raghu Sreeramaneni said HBM needs roughly three times DDR5's wafer area for the same capacity, and when asked whether newer generations close the gap, said it definitely would not get better (Tom's Hardware). An HBM4 die runs 256 memory banks against DDR5's 32. HBM will consume 23% of total DRAM wafer output in 2026, up from about 19%, which is the mechanism behind every consumer memory price story this year.
