Socket AM5 (LGA 1718) is a zero insertion force flip-chip land grid array (LGA)[1] CPU socket designed by AMD that is used for AMD Ryzen microprocessors starting with the Zen 4 microarchitecture.

[5] In March 2017, with the launch of its new Zen processors, AMD used the AM4 socket that they had previously used with their Bristol Ridge (derived from Excavator) powered Athlon X4 and some A-Series, a pin grid array (PGA) socket that they promised to support until 2020.

[6] At CES 2022, AMD CEO Lisa Su unveiled the AM5 socket and the integrated heat spreader design for the upcoming Ryzen 7000 processors due in late 2022.

On May 23, 2022, AMD provided details about the AM5 socket, its corresponding motherboards, and Ryzen 7000 Series CPUs at Computex in Taipei, Taiwan.

[16] Unlike AM4, the backplate on AM5 is not removable, as it also serves the purpose of securing the CPU retention mechanism for the LGA socket.
