According to reports, AMD has partnered with Samsung Electronics to transfer some of its 4 nm processor silicon fabrication from TSMC. TSMC, the leading Taiwan-based foundry, is said to be operating at full capacity for its 4 nm-class nodes, with Apple and Qualcomm among its customers sourcing 4 nm mobile SoCs on the node. This has left AMD with limited allocation and/or bargaining power with TSMC, as the company relies on 4 nm for its Ryzen 7040 series "Phoenix" mobile processors. AMD is currently adapting its design from Samsung's 4 nm-class nodes, of which there are five for AMD to choose from. Switching to Samsung is expected to give AMD more scalability, especially since "Phoenix" has missed its release timeline. As a result, AMD has the 5 nm + 6 nm Ryzen 7045 series "Dragon Range" MCM in the premium segments, and the 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."
