Apple is already testing the initial batch of processors produced for its devices by TSMC Arizona, reports Nikkei Asia. To begin with, the tests intend to compare the Arizona output to see if the quality is similar to chips produced in TSMC’s cutting-edge fabs in Taiwan.

TSMC's chip foundry in Arizona is not just making one Apple chip, as a second Apple design is reportedly now in production at the facility.

Apple is in the "final stages" of verifying the 'Made in America' iPhone chips in the TSMC Arizona factory so it can start using them.

Taiwan Semiconductor Manufacturing Company (TSMC) first announced its plans to build an “advanced semiconductor manufacturing fabrication” facility in Arizona in early 2020, committing to a $12 billion investment in Phoenix that it later increased to a staggering $40 billion when it committed to a second facility in the state.

Apple announced that it would start using US chipsets from TSMC’s Arizona plant in the future. TSMC said that a third of the chips made at the Arizona plant will be for the iPhone maker. At the time,

TSMC's Arizona plant has apparently started making Apple Watch chips. Here's everything we know about Apple US production.
