Socket AM3, which will be used in future AMD CPU releases, is a CPU socket designed by AMD for desktop processors, including the performance, mainstream and value segments. It did have an expected release for January 2009, as a replacement for Socket AM2/AM2+. But currently Socket AM2+ processors (Code Name: Deneb 45 nm) are scheduled for a January 8th 2009 launch, pushing back the release of Socket AM3 to February 2009.
AMD has confirmed that AM3 processors will work on some AM2 motherboards. However, AM2/2+ processors will not work on AM3 motherboards because AM2 processors lack the DDR3 memory controller. Also, two extra pins and the change in contact placement[2] (940 for AM2 processors vs 938 for AM3 processors) makes the older chips mechanically incompatible with the new socket, preventing users from attempting to install an old chip in a new board. As of late 2008, AMD announced all processors including the Deneb FX will offer support for both DDR2 and DDR3. [3] [4]
Socket AM3 will be able to run either DDR2 or DDR3 SDRAM memory [5], but not both on the same motherboard; DDR3 runs at higher clock frequencies while drawing less power than DDR2 memory; however, it also has higher latencies, and is currently somewhat more expensive. Therefore, users of Socket AM2 motherboards will be able to upgrade to AM3 processors, without replacing the motherboard or memory.
