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 processors, including the performance, mainstream and value segments. It was released on May 23, 2006, as a replacement for Socket 939 & Socket 754. == Technical specifications == AM2 processors are incompatible with 939 motherboards and vice versa, and although it has 940 pins, it is incompatible with Socket 940. Socket AM2 supports DDR2 SDRAM memory but not DDR memory, which the previous Socket 939 supported. AnandTech reported that Socket AM2 system performance was only about 7% faster than Socket 939 equivalents, with most applications about 2% faster, despite having over 30% greater memory bandwidth due to DDR2 support. 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). Most processors on Socket AM2 include SSE3 instructions and were developed with 90 nanometer technology. Recent models feature 65 nanometer technology (to compete with Intel and their 65 nm CPUs). Socket AM2 supports AMD Phenom processors but some motherboard manufacturers did not supply newer BIOS files required to operate a Phenom processor. Socket AM2 was a part of AMD's generation of CPU sockets that included Socket F for servers and Socket S1 for mobile computing. There are also single-socket Opteron processors available for AM2. While technical documentation was readily available for earlier generations of AMD processor sockets, the AM2 Processor Functional Data Sheet (AMD document number 31117) has not been made publicly available. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Socket AM2」の詳細全文を読む スポンサード リンク
