The AMD Opteron™ processor, enabling simultaneous 32- and 64-bit computing, represented the landmark introduction of AMD64 with Direct Connect Architecture. The AMD Opteron™ processor was designed to run existing 32-bit applications with outstanding performance and offers customers a simplified migration path to 64-bit computing. This evolutionary processor provided a dramatic leap forward in compatibility, performance, investment protection, and reduced total cost of ownership (TCO). The AMD Opteron™ processor was offered in three series: the 100 series (1-way), the 200 series (Up to 2-way), and the 800 series (Up to 8-way).

AMD continued to drive technology leadership by introducing another computing first: multi-core technology for the x86-based computing market. Dual-core AMD Opteron processors for servers and workstations extend AMD's Direct Connect Architecture by connecting two CPUs on one die, improving overall system performance and efficiency.

In September 2007, AMD introduced Third-Generation AMD Opteron Processors. Our Quad-Core AMD Opteron processors with Direct Connect Architecture deliver outstanding performance, optimal virtualization, enhanced power efficiency, and low TCO – all within a consistent footprint, and power and thermal envelopes.
