Socket AM4 is a PGA microprocessor socket used by AMD's central processing units (CPUs) built on the Zen (including Zen+, Zen 2 and Zen 3) and Excavator microarchitectures.[1][2]

AM4 was launched in September 2016 and was designed to replace the sockets AM3+, FM2+ and FS1b as a single platform. It has 1331 pin slots and is the first from AMD to support DDR4 memory as well as achieve unified compatibility between high-end CPUs (previously using Socket AM3+) and AMD's lower-end APUs (on various other sockets).[3][4] In 2017, AMD made a commitment to using the AM4 platform with socket 1331 until 2020.[5][6][7] AM5 succeeded the AM4 platform in late 2022 with the introduction of the Ryzen 7000 series, however, AMD has continued to release new CPUs for AM4 even after the release of AM5.[8][9][10][11]
