AMD Opteron™ Processor for Servers and Workstations
The AMD Opteron™ processor, enabling simultaneous 32- and 64-bit computing, represents the landmark introduction of AMD64 with Direct Connect Architecture. The AMD Opteron™ processor is designed to run existing 32-bit applications with outstanding performance and offers customers a simplified migration path to 64-bit computing. This evolutionary processor provides a dramatic leap forward in compatibility, performance, investment protection, and reduced total cost of ownership (TCO). The AMD Opteron™ processor is 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 is continuing 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.
