Mobile Sockets
While less commonly discussed by end-users, AMD also uses different sockets for mobile processors in laptops.
It’s important to note that CPU sockets are not interchangeable. A CPU designed for one socket will not physically fit into a different socket. When upgrading or building a PC, it’s crucial to ensure that the CPU and motherboard are compatible.
Socket Features and Evolution
AMD’s socket evolution has been driven by several key factors:
- Memory Support: Transitioning from DDR to DDR2, DDR3, DDR4, and now DDR5.
- Increased Bandwidth: Improvements in HyperTransport and other interconnect technologies.
- Integrated Graphics: The introduction of APUs with integrated GPUs required new socket designs.
- Power Delivery: Sockets need to provide sufficient power to increasingly powerful CPUs.
