Overview
- Several outlets reported on August 10 that TSMC was holding about $1 billion of finished A20 Pro wafers that could not be packaged because required DRAM had not arrived.
- TF International analyst Ming‑Chi Kuo publicly disputed the $1 billion stranded‑wafers figure the same day and said Apple and TSMC plan 2nm production around expected memory shipments.
- Analysts agree the LPDDR5X shortage is real and has already led Apple to cut its 2026 hardware shipment plans and caused delivery slips for some Mac models.
- Apple’s switch to TSMC’s wafer‑level multi‑chip module (WMCM) packaging ties processor and DRAM together at the wafer stage, so late DRAM deliveries directly delay completed units and raise the risk of thin post‑launch iPhone inventory.
- Political and procurement pressure over memory sourcing, including a congressional request for answers by August 21, adds a parallel risk to Apple’s ability to expand suppliers or shift procurement quickly.
