'''Socket A''' (also known as '''Socket 462''') is a [[zero insertion force]] [[pin grid array]] (PGA) [[CPU socket]] used for [[AMD]] [[Central processing unit|processors]] ranging from the [[Athlon Thunderbird#Athlon Thunderbird (2000–2001)|Athlon Thunderbird]] to the [[Athlon#Athlon XP/MP|Athlon XP/MP]] 3200+, and AMD budget processors including the [[Duron]] and [[Sempron]]. Socket A also supports AMD [[Geode (processor)#Geode NX|Geode NX]] embedded processors (derived from the [[Athlon#Mobile Athlon XP|Mobile Athlon XP]]). It compliments (and later supersedes) the prior [[Slot A]] CPU interface used in some Athlon Thunderbird processors. The front-side bus frequencies supported for the AMD Athlon XP and Sempron are 133&nbsp;[[MHz]], 166&nbsp;MHz, and 200&nbsp;MHz. Socket A supports 32-bit CPUs only.

The socket is a [[zero insertion force]] [[pin grid array]] type with 462 pins, hence the alternative name Socket 462. About nine pins in the socket are blocked to discourage accidental insertion of [[Socket 370]] CPUs on Socket A motherboards.

Socket A was replaced by [[Socket 754]] and [[Socket 939]] during 2003 and 2004 respectively, except for its use with Geode NX processors.
