Samsung and SK hynix to Mass Produce 8-high HBM4 in Q2 Next Year

marketbrief.now

Samsung Electronics and SK hynix plan to begin mass production and volume shipments of 8-high HBM4 in the second quarter of next year, targeting Nvidia's Rubin Ultra and Vera Rubin chip platforms. The shift to 8-high configurations reflects cloud providers and AI labs moving away from 4-high and 6-high setups, with future products like AMD's MI450 and OpenAI's planned systems expected to use 12-high HBM4.
