Apple Delays TSMC’s 2nm Chips for iPhone 17 Pro Due to High Costs and Limited Capacity

Apple's plans to incorporate TSMC’s groundbreaking 2nm chips into its iPhone 17 Pro lineup have reportedly been shelved, as the technology's soaring costs and tight production capacity have created significant hurdles. Known for delivering some of the industry’s most advanced custom silicon with its A-series processors, Apple had initially aimed to transition from the current 3nm node to 2nm for its next-generation Pro models. However, recent reports indicate that the company has decided to delay the move until the iPhone 18 Pro in 2026.

Why Apple Delayed TSMC’s 2nm Chips

TSMC’s 2nm process, still in its early stages, has encountered substantial production challenges. Trial manufacturing at the company’s Baoshan plant in Hsinchu, Taiwan, has yielded disappointing results, with yields hovering at just 60%. This means that nearly 40% of the chips produced are defective, rendering the process highly inefficient for the scale Apple requires. Compounding the issue is the staggering cost of production, with each wafer priced at an eye-watering $30,000. Such expenses, combined with the limited output capacity, have made it impractical for Apple to adopt the 2nm process for the upcoming iPhone 17 Pro and iPhone 17 Pro Max.

Instead, Apple is expected to continue utilizing TSMC’s enhanced 3nm node for the A19 Pro chip in its 2025 flagship devices. While incremental performance improvements are anticipated, the leap in efficiency and power promised by 2nm technology will now have to wait until 2026. At the 2024 IEDM conference, TSMC highlighted that its 2nm chips would feature up to 15% more transistors than the current 3nm technology, translating to a 15% boost in performance without increasing power consumption. These advancements are poised to deliver a substantial upgrade once the technology matures and becomes cost-effective.

Implications for Apple

Apple’s decision to delay the adoption of 2nm chips reflects a calculated move to balance innovation with practicality. The company faces the dual challenge of meeting its high production demands while maintaining competitive pricing for its devices. By sticking with the proven 3nm process for another year, Apple ensures stability and avoids passing exorbitant costs onto consumers, all while giving TSMC more time to refine its next-generation manufacturing techniques.

The delay underscores the difficulties even industry giants face when pushing the boundaries of semiconductor technology. Despite the setback, Apple remains well-positioned to benefit from TSMC’s advancements once the 2nm node achieves higher yields and becomes more viable for mass production. For now, the iPhone 17 Pro lineup will continue to showcase Apple’s expertise in optimizing its A-series processors on the existing 3nm platform, setting the stage for the more ambitious leap to 2nm with the iPhone 18 Pro.
