Opteron is the name of the 64-bit Microprocessor developed by AMD.
Opteron is family of 64-bit x86 server uniprocessors and multiprocessors designed by AMD as a successor to the Athlon MP family. Opteron processors are designed for workstations and servers and are a direct competition to Intel's Xeon processors.
Opteron is the name of a family of CPUs within the AMD64 line. Designed by AMD for the server market, it competes with Intel's Xeon. For Socket 940 and Socket 939 Opterons, each chip has a three-digit model number, in the form Opteron XYY.
Opteron is AMD's x86 former server and workstation processor line, and was the first processor which supported the AMD64 instruction set architecture (known generically as x86-64). It was released on April 22, 2003, with the SledgeHammer core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture (codenamed Barcelona) were announced on September 10, 2007, featuring a new quad-core configuration.
AMD's main products include microprocessors, motherboard chipsets, embedded processors and graphics processors for servers, workstations and personal computers, and embedded systems applications. AMD is the second-largest supplier and only significant rival to Intel in the market for x86-based microprocessors.
