4 is a socket processor used by the processor 's first-generation Intel Pentium (60 MHz and 66 MHz) and Pentium Overdrive . Socket was introduced in March 1993.Socket has the following characteristics:
Has 273 pins, with layout 21x21 PGA ( Pin-Grid Array )
Operating voltage used is 5 Volt
Socket 5 is a socket processor used by the processor second-generation Intel Pentium (75 MHz to 133 MHz) and Pentium Overdrive . Socket was introduced in March 1994.Socket has the following characteristics:
Has 320 pins, with layout 37x37 SPGA ( staggered Pin-Grid Array )
Operating voltage used was 3.3 Volt or 3.5 Volt
-6 socket is a socket processor used by the processor Intel 80486DX4 and Intel Pentium Overdrive . Socket was introduced in February 1994. Although introduced, the processor is rarely implemented in a computer system outstanding, considering the market has been using processor Intel Pentium whose performance is faster than the processor 486.Socket has the following characteristics:

Has 235 pins, with layout 19x19 Pin-Grid Array
Operating voltage used is 3.3 Volts
Socket-7 is a socket processor used by the processor Intel Pentium third generation (75 MHz to 233 MHz), processor Intel Pentium MMX , AMD K5 , AMD K6 , Cyrix M1 , Cyrix MII , as well as the Pentium II Overdrive . This socket was introduced by Intel in June 1995.Socket has the following characteristics:
Has 320 pins, with layout 37x37 SPGA ( staggered Pin-Grid Array )
Operating voltage used varies (ranging between 2.8 volts to 3465 volts), because it uses Intel Voltage Regulator Module (VRM) to regulate the voltage. VRM circuit board itself is contained in the motherboard that determines the operating voltage cocok.Saat processors AMD and Cyrix released a processor with a bus speed of 100 MHz or more, they make extensions to the Socket 7 design, which they named as a Super Socket 7 or Super7. This course makes the systems that still use the Socket-7 can use a faster processor, up to 500 MHz (processor AMD K6-3 ), which almost equals the speed of the processor Pentium II that uses slot-1 or Celeron Socket 370
