x86 processor socket definition
<hardware, standard> One of the series of standard sockets
into which you can plug various x86 microprocessors.
These vary in the number of pins, package, voltages, bus
speeds, and supported processors. Motherboards often have
clock multipliers so that the processor runs at a multiple
of the bus speed.
Socket 1, 169 pin LIF/ZIF PGA (17x17), 5v, 16-33 MHz
486 SX, 486 DX, 486 DX2, DX4 Overdrive. Socket 1 was
the first standard Intel 486 socket.
Socket 2, 238 pin LIF/ZIF PGA (19x19), 5v, 25-50 MHz 486 SX,
486 DX, 486 DX2, 486 DX4, DX4 & Pentium Overdrive. Updated
Socket 1, added support for Pentium Overdrive processors.
Socket 3, 237 pin LIF/ZIF PGA (19x19), 3.3/5v, 25-50 MHz 486
SX, 486 DX, 486 DX2, 486 DX4, DX4 & Pentium Overdrive.
Supports 5V & 3.3V processors, considered the latest 486
socket.
Socket 4, 273 pin LIF/ZIF PGA (21x21), 5v, 60/66 MHz Pentium
60/66 and Pentium Overdrive, only 5v.
Socket 5, 296 pin LIF/ZIF, 320 pin LIF/ZIF SPGA (19x19 or
37x37), 3.3v, 50/60/66 MHz Pentium 75 - 133MHz, Pentium
Overdrive, only 3.3v.
Socket 6, 235 pin ZIF PGA (19x19), 3.3v, 25-40MHz. Unpopular
advanced Socket 3, rarely seen / paper spec 486 DX4, Pentium
Overdrive, only 3.3v.
See also Socket 7, Socket 8, Super 7, Slot 1, Slot
2, Slot A.
