'''AM4''' is a socket for [[AMD]]'s mainstream series of microprocessors, serving as a successor to {{\\|Socket FM2+}} and {{\\|Socket AM3+}}.

== Overview ==
<!-- [[File:socket am4.svg|300px|right]] -->
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 {{amd|Excavator|l=arch}}, {{amd|Zen|l=arch}}, {{amd|Zen+|l=arch}}, {{amd|Zen 2|l=arch}}, and {{amd|Zen 3|l=arch}} microarchitectures, although the exact chips supported depends on the accompanying chipset.

== Chipsets ==

=== Support ===
AM4 socket support for a particular microprocessor depends on the chipset compatibility.
