Socket AM3 is a CPU socket for AMD processors. It follows directly from
Socket AM2+. AM3 was launched on February 9th, 2009, alongside the
initial grouping of Phenom II processors designed for it.[3] The sole
principal change from AM2+ to AM3 is support for the AM3 processors'
integrated memory controller, which now supports DDR3 in addition to
DDR2.

Socket FS1
The Socket FS1 is a CPU socket to be implemented in the
future notebook platform from AMD with its Fusion
processors (codenamed Swift).
While the processor will implement a "high-end GPU core
with UVD" functionality, former ATI CEO Dave Orton has
stated that Fusion products will have 10% more pins than a
"normal CPU" but further elaboration on what is a "normal
CPU" was not given.
Server sockets
Socket A Socket 940 Socket F Socket F+ Socket G3 (ยกเลิกผลิต) Socket G34
Socket F+
Socket F+ (also Socket Fr2 internally ) is an upcoming CPU
Socket for AMD server processors starting from the 45 nm
generation of the K10 CPU family. It is the successor to
Socket F. The main difference between the two sockets is
the supported HyperTransport version, while Socket F
supports HyperTransport 2.0 at 1.0 GHz speed, Socket F+
supports HyperTransport 3.0 at up to 2.6 GHz speed and is
backwards compatible with version 1.0 and 2.0.
Socket G3
The Socket G3, originally as part of the codenamed Piranha server platform,
was supposed to be the intermediate successor to Socket F and Socket F+ to
be used in AMD Opteron processor for dual-processor (2P) and above
server platforms scheduled to be launched 2009. The Socket G3 would have
been accompanied by the Socket G3 Memory Extender (Socket G3MX), for
connecting large amounts of memory to a single microprocessor by a G3MX
chip placed on the motherboard.
AMD had planned socket G3 to arrive with the advent of the previously
planned 8-core MCM chip code named Montreal. Since Q1 2008, the plan
for and 8-core MCM server chip based on 45nm K10.5 design has been
scrapped in favor of a 6-core fully-integrated MPU design code named
Istanbul, which will use the existing socket F/F+ platform, produced by
Nvidia, Broadcom, as well as Fiorano to be introduced by AMD in 2009.
However, socket G3 was officially discontinued as of March 2008. The
socket that will be the successor to the Socket F is the LGA 1974-pin Socket
G34.
Socket G34
The Socket G34 is a CPU socket designed by AMD to
support the upcoming six-core and twelve-core
processor lines codenamed Sao Paolo and MagnyCours, while the CPU cores are still based on the K10
microarchitecture, current information suggests that
the processors will support HyperTransport 3.0 and
four-channel DDR3 memory modules. The original
Socket G3 and G3MX were cancelled altogether.
Design of IC sockets
ได้ แก่ ZIF , LAG, PGA
ZIF
ZIF is an acronym for zero insertion force, a concept used in the
design of IC sockets, invented to avoid problems caused by
applying force upon insertion and extraction.
A normal integrated circuit (IC) socket requires the IC to be pushed into
sprung contacts which then grip by friction. For an IC with hundreds of
pins, the total insertion force can be very large (tens of newtons),
leading to a danger of damage to the device or the PCB. Also even with
relatively small pin counts each extraction is fairly awkward and carries
a significant risk of bending pins (particularly if the person performing
the extraction hasn't had much practice or the board is crowded), as can
be seen with the unpopular front-loading mechanism of the Nintendo
Entertainment System. Low insertion force (LIF) sockets reduce the
issues of insertion and extraction but the lower the insertion force of a
conventional socket, the less reliable the connection is likely to be.

PGA
A pin grid array, often abbreviated PGA, refers to the
arrangement of pins on the integrated circuit packaging. In a
PGA, the pins are arranged in a square array that may or may
not cover the bottom of the package. The pins are commonly
spaced 2.54 mm (0.1") apart. PGAs are often mounted on
printed circuit boards via two methods, through hole or by
using a socket. PGAs are primarily used in applications that
require more pins than what older packages such as the dual
in-line package (DIP) provide.

LAG
The LGA is used as a physical interface for microprocessors of
the Intel Pentium 4, Intel Xeon, Intel Core 2, Intel Core i7
and AMD Opteron families. Unlike the pin grid array (PGA)
interface found on most AMD and older Intel processors,
there are no pins on the chip; in place of the pins are pads of
bare gold-plated copper that touch pins on the motherboard.
While LGA sockets have been in use as early as 1996 by the
MIPS R10000 and HP PA-8000 processors, the interface did
not gain widespread use until Intel introduced their LGA
platform starting with the 5x0 and 6x0 sequence Prescott
core Pentium 4 in 2004. All Pentium D and Core 2 desktop
processors currently use an LGA socket. As of Q1 2006 Intel
switched the Xeon server platform to LGA starting with the
5000-series models. AMD introduced their server LGA
platform starting with the 2000-series Opteron in Q2 2006.
AMD offers the Athlon 64 FX-74 on socket 1207FX through
ASUS's L1N64-SLI WS motherboard as the only desktop LGA
solution in the desktop market from AMD currently.
The most common Intel desktop LGA socket is dubbed LGA 775 (Socket
T) while the server variant is dubbed LGA 771 (Socket J). However, the new
Intel Core i7 family uses the LGA 1366 (Socket B) socket. Intel supposedly
decided to switch to an LGA socket because it provides a larger contact point,
allowing, for example, higher clock frequencies. The LGA setup provides higher
pin densities, allowing more power contacts and thus a more stable power
supply to the chip. Motherboard vendors have complained that LGA packaging
was introduced solely to move the burden of bent pin problems from Intel to the
electronics vendors.
The AMD server LGA socket is designated Socket F (LGA 1207) Similar to Intel,
AMD decided to use an LGA socket because it allows higher pin densities. The
required size of a 1207-pin PGA would simply be too large and would consume
too much space on motherboards.
