HBM shake-up: SK Hynix HBM4 packaging delays reported, prices seen up 30-45% in 2027
tengyanAI · x · 2026-10-19
A digest of expert chatter on the HBM trade, sourced via AI:
- SK Hynix execution risk: reported HBM4 packaging-equipment delays (volumes sliding from H2 2026 into 2027) could open the door for Samsung; DigiTimes corroborates a possible deferral but not lost customer allocations
- Prices up: analysts forecast HBM3E/HBM4 prices rising 30-45% in 2027, a major revenue tailwind partially offset by higher manufacturing costs
- Nvidia demand: Rubin Ultra packs 384GB HBM4E vs. Rubin's 288GB — 33% more memory per accelerator
- China: CXMT reportedly prepping DDR5 RDIMMs but estimated 5-7 years behind Samsung per KB Securities
Higher prices and content benefit the whole industry, but Hynix stumbles could hand Samsung and Micron a disproportionate share.
