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, reports Tim Culpan, a well-connected journalist, citing his own sources.
If the information is accurate, then TSMC's Fab 21 in the U.S. is now producing at least three chips: Apple's A16 Bionic system-on-chip for iPhone 15 and iPhone 15 Plus smartphones, at least one IC in the Apple S9 SiP for smart watches (we presume this is the actual application processor with two 64-bit cores and a quad-core neural engine), and one of AMD's Ryzen 9000-series CPU. All of the said processors are made using TSMC's 4nm-class N4 and N4P technologies.
