Independent tech journalist Tim Culpan pointed out that the A20 Pro processor wafers produced by TSMC’s N2 process are showing good yield and sufficient capacity, with processor production basically ready, and that this process is not a bottleneck affecting iPhone shipments. However, due to a severe shortage of DRAM supply, the completed processor wafers cannot be subsequently packaged, leading to inventory buildup and putting pressure on Apple and its supply chain’s stockpiling. With only weeks to go before the release of the iPhone 18 series and the foldable iPhone Ultra, Apple and its supply chain assemblers are urgently seeking more mobile DRAM chip supply. In terms of DRAM supply, Apple currently relies primarily on Micron Technology, while also sourcing from SK Hynix and Samsung.
