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.
