Processor Socket Platforms:

August 14, 2005

Socket 775 also known as Socket T and LGA 775, is Intel's latest CPU socket. LGA stands for Land Grid Array, which means that the pins are on the motherboard, not the processor. The Prescott (Pentium 4 core) is the only processor to use the LGA 775 socket type, for now. LGA 775 offers a Front side bus of 1066 MHz and the new pin type has better power distribution to the processor.

Note: Most LGA 775 motherboards support DDR2 memory.

Socket 478 is a type of CPU socket used for Intel's Pentium 4 and Celeron series CPUs. It has been used for all of the Northwood Pentium 4s and Celerons, the first Prescott Pentium 4s, and some Willamette Celerons and Pentium 4s. Socket 478 also supports newer Prescott Celeron Ds, and early Pentium 4 Extreme Edition processors with 2MB of L3 cache. The socket was launched with the Northwood core to combat AMD's 462-pin Socket A and their Athlon XP processors. Socket 478, which accommodates high- and low-end processors, was also the replacement for Socket 423, a Willamette processor socket that did not have a long life.

Note: All 478 motherboards support DDR memory.

Socket 939-based motherboards are designed to provide performance enhancements for AMD Athlon 64 FX and AMD Athlon 64 processor-based systems.

  • PCI Express graphics solutions
  • Cool’n’Quiet™ technology
  • Up to 2.0 GHz HyperTranport technology providing up to 8.0GB/s of system bandwidth
  • Dual-channel, unbuffered DDR memory providing up to 6.4GB/s of memory bandwidth

Socket 754 was originally developed by AMD to succeed its powerful Athlon XP platform. Socket 754 was the first socket developed by AMD to support their new consumer version of the 64 bit microprocessor family known as AMD64.

Socket 754 is a budget-minded socket, for use with AMD Athlon 64 or Sempron processors . Compared to Socket 939, it features:

  • Support for a single channel memory controller (64-bits wide) with maximum of 3 DIMMs
  • Lower HyperTransport speed (800 MHz Bi-Directional, 16 bit data path, up and downstream)
  • Lower effective data bandwidth (9.6 GB/s)

Socket A (also known as Socket 462) is the CPU socket 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.
