Apple's Upcoming A20 Chip May Significantly Increase iPhone 18 Costs

Apple's next-generation A20 chip, slated for the iPhone 18 series, is anticipated to be the first widely available 2-nanometer processor, succeeding the previous three generations of A-series chips based on TSMC's 3-nanometer node. This advancement is expected to deliver enhanced performance and efficiency.

TSMC has reportedly informed clients, including Apple, to prepare for a cost increase of at least 50% compared to 3-nanometer processors. This rise is attributed to substantial capital expenditures for the new node and the absence of discounting strategies during the initial yield phase.

Suppliers project that flagship mobile chips produced with the 2-nanometer process will have unit prices around $280 once mass production commences. This would position the A20 chip as the most expensive component in the iPhone, potentially affecting Apple's profit margins if the increased costs are not transferred to consumers.

A previous report estimated the A18 chip's cost at approximately $45, with a total hardware bill of $416 for a model retailing at $799. This suggests that the chip accounted for roughly 10% of the bill of materials and about 5–6% of the retail price, prior to logistics and development expenses. The rear camera assembly was identified as the most expensive component in that analysis.

If these cost projections hold, Apple may restrict the 2-nanometer chips to select 2026 iPhone models, such as the iPhone 18 Pro and iPhone 18 Pro Max. In September of the previous year, Apple analyst Ming-Chi Kuo cautioned that "due to cost concerns, not all new iPhone 18 models may be equipped with a 2-nanometer processor."
