iOS 27 will bring tighter system-level integration with Apple Intelligence. My latest industry checks suggest Apple's lower-end 1H27 iPhones, powered by the A20 chip, will move to 9GB DRAM (1.5GB × 6 dies), up from 8GB (2GB × 4 dies) in the current A19 models, to keep the system running smoothly under AI workloads. The three new high-end 2H26 models powered by the A20 Pro chip (the foldable and two 18 Pro models) will remain unchanged at 12GB (1.5GB × 8 dies).
