servers run smooth today and tomorrow. 
* X86-64 Technology

The AMD x86-64 architecture is an AMD innovation that extends x86, the 

industry's most widely supported instruction set, and is designed to 

enable 64-bit computing while remaining compatible with the existing x86 

software infrastructure and industry experience.

AMD's 64-bit strategy allows the latest in processor innovation to work 

smoothly with the existing installed base of 32-bit applications and 

operating systems, while establishing an installed base of systems that 

are 64-bit capable.

AMD X86-64 Technology enables the industry to advance software 

development on all fronts, with x86 compatibility, while providing the 

capability of delivering 64-bit technology benefits.
* AMD HyperTransport Technology

HyperTransport technology is a high-speed, low latency, point-to-point 

link designed to increase the communication speed between integrated 

circuits in computers, servers, embedded systems, and networking and 

telecommunications equipment up to 48 times faster than some existing 

technologies. 

HyperTransport technology helps reduce the number of buses in a system, 

which can reduce system bottlenecks and enable today's faster 

microprocessors to use system memory more efficiently in high-end 

multiprocessor systems. 

HyperTransport technology is designed to: 

- Provide significantly more bandwidth than current technologies.

- Use low-latency responses and low pin counts 

- Maintain compatibility with legacy PC buses while being extensible to 

new SNA (Systems Network Architecture) buses. 

- Appear transparent to operating systems and offer little impact on 

peripheral drivers. 
* Integrated DDR DRAM

As processor microarchitecture capabilities have advanced, one of the 

greatest performance limitations has become the system architectures 

ability to provide sufficient low-latency memory bandwidth to the 

processor core. The AMD Athlon 64 processor and the AMD Opteron

processor directly addresses this bottleneck by integrating a DDR memory 

controller into the processor, revolutionizing the way x86-based 

processors access main memory. By running at the processor s core 

frequency, an integrated memory controller greatly increases bandwidth 

directly available to the processor at significantly reduced latencies. 

The performance-enhancing effect is even more dramatic within an AMD 

Opteron multiprocessing environment, because each additional processor 

has its own memory controller thereby scaling over all memory bandwidth. 

Features of Integrated DDR DRAM Memory Controller:

- Available memory bandwidth scales with the number of processors added.

- 128-bit wide integrated DDR DRAM memory controller capable of 

supporting up to eight (8) registered DDR DIMMs per processor.

- Available memory bandwidth up to 5.3GB/s (with PC2700 memory) per 

processor.
