AMD is having some of its latest Ryzen 9000-series desktop CPUs made at TSMC's new fab in Arizona. So claims Taipei, Taiwan-based journalist Tim Cuplan. It was reported last year that AMD was planning on having some high-performance CPUs made at TSMC's Arizona facilities.

TSMC Arizona has just picked up its second contract from Apple: fab will make SiPs (Systems-in-Package) for Apple Watch, as well as A16 chips for iPhones.

The news comes in the same week that independent journalist Tim Culpan reported that the chipmaker has secured a second Apple product for production at its Arizona fab, with the previously reported AMD product now being named as the Ryzen 9000, codenamed Grand Rapids.

TSMC's Fab 21 in Arizona is gradually ramping up production, and recently it began to manufacture some of AMD's Ryzen 9000-series processors for client PCs as well as some ingredients of Apple's S9 system-in-package (SiP) for smart watches,

AMD getting Ryzen 9000 series chips is another feather in the Arizona fab’s cap and suggests that confidence in TSMC’s U.S. operations is strong. According to Culpan, the fab is producing about 10,000 wafers a month and, according to plans for Phase 1, will eventually get to 24,000 per month.

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 has expanded its production footprint in the United States, with its S9 chip for the Apple Watch now reportedly being manufactured
