Samsung’s improved 4nm process attracts AMD for Zen 5c chips

AMD is expected to produce “Zen 5c” server chips, known by the code name Prometheus, in Samsung Electronics’ foundry’s 4nm and TSMC’s 3nm process. The company has mainly used TSMC as its main foundry company, but this time, it is exploring ways to place orders from Samsung as well.

The reason why AMD produces the product in TSMC’s 3nm process and Samsung’s 4nm process is interpreted as a strategy of dividing the products into high-end and entry-level products, leaving premium products to TSMC and low-end products to Samsung.

Samsung’s 4nm foundry process has achieved improvements in performance and yield this year. If Samsung Electronics successfully supplies Zen 5c chips to AMD, there is a possibility of new orders based on 3nm Gate All Around (GAA) in the future.

Another positive factor is that Samsung has significantly improved production stability in advanced processes such as 5nm, 4nm, and 3nm processes this year. The industry predicts that the company’s 4nm process yield this year has exceeded 70%, and the 3nm GAA process yield is also close to 70%.
