Apple A20 Pro Leak Shows 96-Bit Memory Bus and 12 GB RAM

Summary
A package-layout leak says Apple’s A20 Pro for the iPhone 18 Pro line will use a 96-bit memory interface and 12 GB of RAM, a notable step up from prior Pro chips’ 64-bit bus.
That wider interface could lift memory bandwidth by as much as 50% before any speed gains from the memory standard itself, though leakers disagree on whether Apple will use LPDDR6 or stay with LPDDR5X.
The same leak points to wafer-level multi-chip packaging that places memory dies beside the SoC instead of stacking them, a change aimed at better heat dissipation and potentially more flexible future memory layouts.
The die appears roughly unchanged from the A19 Pro’s estimated 98.6 mm², suggesting bigger gains may come from new CPU and GPU cores, a stronger NPU, and TSMC’s N2 process.
