TSMC 2nm Monthly Output Exceeds 20,000 Wafers; Google Pixel 11 and iPhone 18 to Adopt; 3% Revenue in Q3 2026

TSMC's 2nm process has entered a rapid ramp-up phase, with its Fab 20 in Taiwan reaching a monthly output of over 20,000 wafers. Tape-out volumes for 2nm are four times those of 3nm at the same stage. In the third quarter of 2026, 2nm is expected to contribute about 3% of TSMC's revenue, primarily from early design verification and tape-out fees. The Google Pixel 11 series, planned for an August release, will use the Tensor G6 chip, while Apple's iPhone 18 series, set for September, will feature the A20 Pro chip. AMD has announced its MI455X GPU for Agentic AI will use TSMC's 2nm process, and Nvidia's next-generation Rubin platform is also in line. Currently, 3nm remains TSMC's main production capacity with a monthly output of 175,000 wafers.
