#TSMC's #Fab21 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 and Apple's A16 Bionic system-on-chip for iPhone 15 and iPhone 15 Plus smartphones
All of the said processors are made using TSMC's #4nm-class #N4 and #N4P technologies.
