Socket 7 is a physical and electrical specification for an
Pentium microprocessors manufactured by Intel, as well as compatibles made by Cyrix/IBM, AMD, IDT and others.[2]
Socket 7 was the only socket that supported a wide range of CPUs from different manufacturers and a wide range of speeds.
Differences between Socket 5 and Socket 7 are that Socket 7 has an extra pin and is designed to provide dual split rail voltage, as opposed to Socket 5's single voltage. However, not all motherboard manufacturers supported the dual voltage on their boards initially. Socket 7 is backwards compatible; a Socket 5 CPU can be inserted and used on a Socket 7 motherboard.
Processors that used Socket 7 are the
Pentium (2.5–3.5 V, 75–200 MHz), the Pentium MMX (166–233 MHz), and the Rise Technology mP6
.
Socket 7 typically uses a 321-pin (arranged as 19 by 19 pins)
SPGA LIF
socket. The size is 1.95" x 1.95" (4.95 cm x 4.95 cm).
An extension of Socket 7, Super Socket 7, was developed by AMD for their K6-2 and K6-III processors to operate at a higher clock rate and use AGP.
Socket 7 and Socket 8 were replaced by Slot 1 and Slot 2 in 1999.
