Leaked Code Maps Apple Chip Allocations as A20 Prepares for 2nm WMCM Packaging

Leaked code outlines chip allocations across upcoming Apple TV, iPad, Studio Display and Vision Pro models with Ming-Chi Kuo predicting the A20 will adopt WMCM packaging on TSMC’s 2nm node

Overview

  • An accidental code leak shared by @aaronp613 reveals that Apple plans to use the A17 Pro in a refreshed Apple TV 4K and the A18 chip for its next low-cost iPad, likely launching in spring 2026.
  • The same leak indicates the next-generation iPad mini and second-generation Studio Display will feature the unreleased A19 Pro, while the Vision Pro 2 is set to run on Apple’s M5 chip.
  • Analyst Ming-Chi Kuo projects that the A20 will switch from InFO to WMCM packaging and be manufactured on TSMC’s 2nm process, promising integrated RAM, higher bandwidth and improved power efficiency.
  • According to Kuo’s timeline, WMCM-packaged A20 chips will debut in iPhone 18 Pro and foldable models in the second half of 2026, with standard iPhone 18 variants following in spring 2027.
  • These insights remain unconfirmed by Apple and are based on interpretations of leaked code and supply-chain analysis, highlighting the need for official announcements to verify device and chipset plans.
