Chosun Biz suggests that for its 4nm process, Samsung aims to win orders by enhancing power efficiency by about 20% with the SF4U. According to Samsung, SF4U is a premium 4nm variant using optical shrink technology to enhance PPA (power, performance and area), with mass production planned for 2025.
Although Samsung’s 4nm, 5nm, and 7nm nodes trail TSMC in chip performance, the company competes by pricing them about 30% lower and maintaining yields above 70% amid fierce price battles, the report notes. According to an industry insider cited by Chosun Biz, Samsung’s 4nm and 5nm processes have improved enough to rival TSMC, giving it a key advantage as Chinese competitors have yet to develop these nodes.
