The Socket AM2, renamed from Socket M2, is a CPU socket designed by AMD for desktop processors, including the performance, mainstream and value segments. It was released on May 23, 2006, as a replacement for Socket 939 & Socket 754. Although it has 940 pins, it is incompatible with Socket 940, to support dual channel DDR2 RAM of up to DDR2 800. DDR2 runs at higher clock frequencies drawing less power than DDR memory, on which the previous Socket 939 ran on. AnandTech reported that Socket AM2 system performance was 0-7% faster than Socket 939 equivalents with most applications about 2% faster [1][2], despite having over 30% greater memory bandwith due to DDR2 support. While future samples and the final product may prove to be faster, significant gains are not expected until later revisions take advantage of the surplus bandwidth.
The first processor cores to support socket AM2 are the single-core Orleans (Athlon 64) and Manila (Sempron), and the dual-core Windsor (Athlon 64 X2 and Athlon 64 FX). All processors on Socket AM2 were developed with 90 nm technology and include SSE3.
Socket AM2 is a part of AMD's next generation of CPU sockets, along with Socket F for servers and Socket S1 for mobile computing.
