Socket 7 is a physical and electrical specification for an x86-style CPU socket on a personal computer motherboard. It was released June 1995. the socket supersedes the earlier Socket 5, and accepts P5 Pentium microprocessors manufactured by Intel, as well as compatibles made by Cyrix/IBM, AMD, IDT and others. 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 placed in a Socket 7 motherboard. Processors that used Socket 7 are the AMD K5 and K6, the Cyrix 6x86 and 6x86MX, the IDT WinChip, the Intel P5 Pentium (2.5–3.5 V, 75–200 MHz), the Pentium MMX (166–233 MHz), and the Rise Technology mP6. Current AMD Geode LX and Geode GX still use Socket 7. Socket 7 typically uses a 321-pin (arranged as 19 by 19 pins) SPGA ZIF socket or the very rare 296-pin (arranged as 37 by 37 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. ==See also== * List of Intel microprocessors * List of AMD microprocessors 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Socket 7」の詳細全文を読む スポンサード リンク
