Ming-Chi Kuo: Base iPhone Model to Get 9GB RAM by 2027, A20 Chip to Drive On-Device AI Inference Demand
N.R. Finch
Supply-chain research by Ming-Chi Kuo shows the A20-powered base iPhone in H1 2027 will step up from 8 GB to 9 GB of memory, driven by iOS 27 and Apple Intelligence's heavier bandwidth demands — the base model is closing in on flagship specs.
How is the base iPhone's memory changing?
The current A19 model carries 8 GB (2 GB × 4 dies); the 2027 A20 model rises to 9 GB (1.5 GB × 6 dies).
This means → the extra gigabyte comes not from larger dies but from packing in two more, smaller ones.
In plain terms = Apple chose a "more but smaller" die layout to squeeze out additional capacity.
Why add memory right now?
The driver is iOS 27's deep system-level integration with Apple Intelligence — on-device AI inference needs more bandwidth and capacity.
This means → Apple has concluded that 8 GB can no longer run the next wave of on-device AI features; the base model must close that gap.
This reflects AI inference spreading down from flagships to become a baseline requirement across the entire lineup, not a premium-only feature.
Are the flagships changing too?
Three A20 Pro flagships due in H2 2026 — including a rumored foldable and two iPhone 18 Pro models — stay at 12 GB (1.5 GB × 8 dies).
This means → the memory boost is confined to the low end; flagships already have enough headroom.
In plain terms = flagships hold steady at 12 GB while the base model climbs from 8 GB — the gap is narrowing.
What trade-off is hidden in the new die layout?
The base model switches from 4 × 2 GB dies to 6 × 1.5 GB dies — per-die capacity actually shrinks.
This means → Apple is balancing cost against AI inference performance — more small dies lift the total while avoiding the cost jump of larger individual dies.
Whether this lets the base model meaningfully close the Apple Intelligence experience gap with flagships will be the key question of the 2027 product cycle.
