This article is part of the CPU socket series

Socket A (also known as Socket 462) is used for AMD flagship processors ranging from the Athlon K7 to the Athlon XP 3200+, and AMD budget processors including the Duron and Sempron. The socket is a zero insertion force pin grid array type with 462 pins.

Socket A is, as of Q4 2004, slowly being replaced by newer socket types such as Socket 754 used by Sempron and Athlon 64 processors, and Socket 939 used by Athlon 64 and Athlon 64 FX processors.

Technical Specs

• Support of processor clock-speeds between 600MHz (Duron) to 2333MHz (Athlon XP 3200+)
• double data rate 100MHz, 133MHz, 166MHz and 200MHz front side bus on Duron through to Athlon XP processors, based on the DEC Alpha EV6 bus.
• The platform upon which the first 1.0GHz x86 processor operated.
