Investment protection  

By leveraging AMD’s Common Core Strategy and Same Socket Technology, Quad-Core Opteron 

processors can minimize changes to the customer’s software and data center infrastructure, 
protecting IT investments and simplifying management.  

AMD Dual Dynamic Power Management 
Dual Dynamic Power Management functionality allows each processor to maximize the power-saving 
benefits of Enhanced AMD PowerNow! without compromising performance, reducing idle power 

consumption and enabling per-processor power management in multi-socket systems to further reduce 

power consumption.  
By powering core and memory controller voltage planes independently, Dual Dynamic Power 
Management can enhance both performance and power management. 
Benefits include: 
• 

Increased performance 

The memory controller is able to run at a higher frequency, helping to reduce memory latency and 

thus improving application performance. 

• 

Improved power management 

By operating independently from the memory controller, the cores in a Quad-Core Opteron 

processor can exploit the power savings offered by Enhanced PowerNow! more often, resulting in 

reduced power and cooling bills. In addition, the processor reduces power to the northbridge

 

when memory is not in use, while continuing to provide full power to the cores. 

The following sections of this paper describe the testing performed by HP to characterize the 

performance and scalability of an HP ProLiant BL685c G5 server blade in a 64-bit HP SBC 

environment.  

Note: 

A 64-bit HP SBC environment eliminates the kernel memory constraints that 
can limit server scalability in a 32-bit HP SBC environment. For more
