AMD Opteron™ Processors

Next-Generation AMD Opteron™ processors add important new features like quad-core upgradeability, AMD Virtualization™ (AMD-V™), and energy-efficient DDR2 memory to the proven technologies introduced in 2003 with first-generation AMD Opteron processors.
The advanced technologies in opteron processors:

AMD64 technology
Runs existing installed base of 32-bit applications and operating systems at peak performance, while providing a 64-bit capable migration path
Designed to enable 64-bit computing while remaining compatible with the vast x86 software infrastructure
Enables a single architecture across 32- and 64-bit environments

Direct Connect Architecture
AMD’s revolutionary Direct Connect Architecture helps eliminate the bottlenecks inherent in traditional front-side bus architectures
Direct Connect Architecture connects the processors, integrated memory controller, and I/O directly to the CPU and communicates at CPU speed
HyperTransport™ technology provides a scalable bandwidth interconnect between processors, I/O subsystems, and other chipsets, with up to three coherent HyperTransport technology links providing up to 24.0 GB/s peak bandwidth per processor

Integrated Memory Controller - Integrated on-die DDR2 DRAM memory controller offers available memory bandwidth up to 10.7 GB/s (with DDR2-667) per processor
AMD Opteron™ processors with DDR2 memory are designed to offer a seamless upgrade path from dual-core to quad-core when they are available in 2007 in the same thermal envelope to help leverage existing investments
Offers a significant performance improvement while maintaining the same platform at the same power efficiency
