AMD has reportedly signed up with Samsung Electronics to shift some of its 4 nm processor silicon fabrication from TSMC. The apex Taiwan-based foundry is reportedly operating at capacity for its 4 nm-class nodes, with customers such as Apple and Qualcomm sourcing 4 nm mobile SoCs on the node, leaving AMD with limited allocation and/or bargaining power with TSMC. The company relies on 4 nm for its Ryzen 7040 series "Phoenix" mobile processors, and is in the process of adapting its design from Samsung's 4 nm-class nodes (of there are five for AMD to choose from). Switching to Samsung probably gives AMD more scalability, particularly given that "Phoenix" has missed its release timeline, leaving AMD with the 5 nm + 6 nm Ryzen 7045 series "Dragon Range" MCM in the premium segments, and older 6 nm 7035 series "Rembrandt-R" in the mainstream and ultraportable segments, but nothing "apt" to compete against "Raptor Lake-U" and "Raptor Lake-P."
