CPU AMD Dual Core Processors

AMD Athlon 64 X2 dual-core processors are identified by a 4 digit model number. AMD model numbers, based on industry-standard benchmarks on a wide range of popular software, are a simple, accurate representation of relative AMD processor performance in a processor family.

The model number methodology is designed to help end users simplify their PC purchase decision.

Higher model numbers are indicative of relative performance of AMD processors in a processor family.

The "+" at the end of each model number indicates the added performance benefits delivered by AMD's innovative processor designs.

AMD Athlon Dual Core Socket AM2 Proccessors

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.

AM2 was released on May, 2006, as a replacement for Socket 939 and Socket 754. Although it has 940 pins, it is incompatible with the AMD Socket 940, AM2 supports dual channel DDR2 RAM which the older Socket 940 did not .

Socket AM2 processors from AMD will support DDR2 speeds of 400MHz, 533MHz, 667MHz and, for AMD Athlon™ 64 X2 dual-core and AMD Athlon™ 64 FX dual-core processors, 800MHz.

The first processor cores to support socket AM2 were 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 ones feature 65 nanometer technology.

Socket AM2+ is the immediate successor to Socket AM2 currently used in several AMD processors such as Athlon 64 X2, Socket AM2+ will be a mid migration from Socket AM2 to Socket AM3 and will be fully compatible with Socket AM2, so processors designed for Socket AM2 will work on Socket AM2+ motherboards and vice versa.

Socket AM2+ will have some differences however that will be used in AM2+ chips, there are two main features in Socket AM2+ not in Socket AM2:

  • HyperTransport 3.0 operating at up to 2 GHz
  • Advanced power features summarized as having split power planes, probably one for CPU Cores, and the other for the Integrated Memory controller (IMC), this will help for more advanced power management control.

AMD confirmed that AM2 processors will work in AM2+ motherboards and AM2+ processors will work on AM2 motherboards. However, due to the lack of support of HyperTransport 3.0 and separated power planes in Socket AM2 motherboards, AM2+ chips will be limited to the specifications of Socket AM2 (HyperTransport 2.0 at the speed of 1 GHz, one power plane for both Cores and IMC). AM2 chips will not benefit from faster HyperTransport and separated power planes on AM2+ motherboards as they do not support them, AM2+ motherboard then fall back to compatibility mode using AM2 specifications.

According to confirmations from AMD, Socket AM2+ will have a compatibility path with Socket AM3, AM3 processors will work in AM2+ motherboards; however, AM2+ processors will not be compatible with AM3 motherboards.
