AMD Set to Become TSMC's Second Major Customer at Arizona Fab, Boosting US AI Chip Production

AMD Poised to Become TSMC's Second Major Customer at Arizona Fab

Advanced Micro Devices (AMD) is set to become the second major customer for Taiwan Semiconductor Manufacturing Company's (TSMC) new fabrication plant in Arizona, following Apple. This development marks a significant step towards establishing a robust artificial intelligence (AI) chip supply chain in the United States 1
