Succession

AM4 is a socket for AMD's mainstream series of microprocessors, serving as a successor to Socket FM2+ and Socket AM3+. It was superseded by Socket AM5.

Overview[edit]

Launching in September 2016, the AM4 replaces a number of older AMD sockets including the Socket FM2+ and Socket AM3+ designed to unify all its mainstream processors from the low-end to the high-end in a single socket. At the time AMD stated the socket will feature prolong comparability life.

The AM4 accepts zero-insertion force µOPGA-1331-packaged microprocessors designed based on the Excavator, Zen, Zen+, Zen 2, and Zen 3 microarchitectures, although the exact chips supported depends on the accompanying chipset.
