Leaked iPhone 18 Pro Board Shows A20 Pro on 2nm WMCM, Promising 15% Faster Performance

Summary
A leaked iPhone 18 Pro motherboard image suggests Apple’s A20 Pro will adopt TSMC’s WMCM packaging, shifting DRAM beside the processor instead of stacking it on top.
That layout should cut thermal coupling and latency under sustained loads, while LPDDR6 memory on a 96-bit bus points to more efficient bandwidth.
TSMC’s 2nm N2 process is also expected to power the A20 Pro, with gains of up to 15% faster performance and 30% better efficiency than A19 chips.
The chip appears similar in size to the A19 Pro, but a notably larger NPU hints at a stronger AI focus alongside SHPMIM capacitors for steadier power delivery.
Apple’s iPhone 18 Pro, Pro Max and foldable iPhone are expected in September with 12GB RAM, 48-megapixel rear cameras and the C2 modem, though the leak remains unverified.
