The Socket AM3, is a CPU socket designed by AMD for desktop processors, including the performance, mainstream and value segments. In Electronic engineering, DDR3 SDRAM or double-data-rate three Synchronous dynamic random access memory is a Random access memory Phenom (pronounced as IPA/finɒm/ as in the word phenomenon) is the AMD desktop processor line based on the K10 ( not "K10h") microarchitecture The Athlon 64 X2 is the first dual-core desktop CPU manufactured by AMD. Sempron has been the marketing name used by AMD for several different entry level desktop CPUs using several different technologies and CPU socket The Opteron is AMD 's X86 server processor line and was the first processor to implement the AMD64 Instruction set architecture (known A CPU socket or CPU slot is a connector on a computer's Motherboard that accepts a CPU and forms an electrical interface with it A CPU socket or CPU slot is a connector on a computer's Motherboard that accepts a CPU and forms an electrical interface with it It has an expected release in late 2008, as a replacement for Socket AM2/AM2+. 2008 ( MMVIII) is the current year in accordance with the Gregorian calendar, a Leap year that started on Tuesday of the Common The Socket AM2, renamed from Socket M2 (to prevent using the same name as Cyrix MII processors is a CPU socket designed by AMD for desktop Socket AM2+ is a CPU socket, which is the immediate successor to Socket AM2 that is currently used by several AMD Processors such as Athlon AM3 should be able to run either DDR2 or DDR3 SDRAM memory, but not both on the same motherboard; DDR3 runs at higher clock frequencies while drawing less power than DDR2 memory, however it is currently much more expensive. In Electronic engineering, DDR3 SDRAM or double-data-rate three Synchronous dynamic random access memory is a Random access memory SDRAM refers to synchronous Dynamic random access memory, a term that is used to describe dynamic random access memory that has a synchronous interface

Socket AM3 is a part of AMD's next generation of CPU sockets.

AMD has confirmed that AM3 processors will work in AM2 motherboards; however, AM2 processors will not be compatible with AM3 motherboards. This is because AM2 chips lack the proper memory controller for DDR3 memory (since current generation AMD chips have the memory controller directly on the processor itself, instead of on the Northbridge), and AM3 processors will have a memory controller that supports both DDR2 and DDR3 (though it lacks the capability of running both at the same time). The memory controller is a chip on a computer's Motherboard or CPU die which manages the flow of data going to and from the memory. This has the benefit that buyers of current Socket AM2 motherboards will be able to upgrade to AM3 processors, without replacing the motherboard. They will not enjoy DDR3 memory without an AM3/DDR3 board, but they can take advantage of other features of faster processors, ensuring AM2 boards a longer life than without the compatibility. Revealed from official presentations ^[1], Socket AM3 will also include DDR2 SDRAM support, and, depending on the adoption rate of DDR3 SDRAM, there is also the possibility to support both SDRAM standards.

Socket AM3 is assumed to be introduced with AMD's next generation processors based on the 45 nm fabrication process.
