Final answer:
The AMD socket that uses a land grid array is the Socket AM5, which differs from previous AMD sockets like the AM4 that used a pin grid array. This change may offer benefits in durability and electrical contact for high-performance computing.
Step-by-step explanation:
The AMD socket that uses a land grid array (LGA) rather than a pin grid array (PGA) is the Socket AM5. Unlike PGA sockets, where the pins are on the processor, LGA sockets have pins on the socket itself, while the processor has pads that make contact with these pins.
AMD's introduction of Socket AM5 represents a move similar to what Intel has used with their LGA sockets for several generations of processors. AMD's previous sockets, like AM4, used PGA, where the pins are on the CPU, requiring careful handling to prevent damage.
The shift to LGA by AMD with Socket AM5 is significant as it can offer benefits in terms of durability and potentially better electrical contacts, which are critical for high-performance computing.
