AMD Opteron™ 4000 Series Platform Technologies 

 

AMD-P 2.0


FEATURE FUNCTION  BENEFIT
APML (Advanced Platform Management Link)  Provides an interface for processor and Systems Management  monitoring and controlling of system resources (in APML-enabled platforms); Comprised of the Remote Power Management Interface (RPMI) and the Precision Thermal Monitor Remote Power Management Interface (RPMI):
  • Ability to monitor and control platform power consumption via p-state limits
  • Access to processor identification and health

Precision Thermal Monitor:

  • Provides accurate information about  CPU thermals to closely monitor power/cooling and proactively alert the Base Management Controller (BMC)
  • Early notification helps save time and money by providing intelligence that can be used to more effectively monitor power and thermals to optimize cooling solutions in an IT datacenter
Link Width PowerCap  Power efficiency capability (manually enabled thru BIOS) which changes all 16-bit links to 8-bit links Link Width PowerCap can help power conscious customers improve performance-per-watt
AMD CoolSpeed Technology Reduces p-states when a temperature limit is  reached
  • Server can continue to operate if processor’s thermal environment exceeds safe operational limits.
  • Offers platform providers the ability to safely reduce system fan speeds which helps deliver greater platform efficiency
C1E  A sleep state invoked when all processor cores are idle This feature can deliver additional power savings (up to 10W for 2P servers1) in your datacenter depending on system configuration, when the Northbridge and HyperTransport™ technology links are powered down and cores are at idle.
LV-DDR3 support Lower memory voltage of 1.35V vs.  standard memory at 1.5V Helps to reduce overall power consumption
Ultra-low power platform Specialized ultra-low power platforms great for cloud/dense environments Cooperative designs for specialized and ultra-low power platform providing power efficiency beyond just the processor


Direct Connect Architecture 2.0


FEATURE FUNCTION  BENEFIT
Up to DDR-3 1333 (1.333 ghz) memory support Provides higher peak throughput than earlier memory technologies Enables improved overall system performance and investment protection compared to earlier technologies
HyperTransport™ Technology Assist (HT Assist) Helps to increase coherent memory bandwidth and reduce latency in multi-node systems by reducing cache probe traffic between cores Reduces the amount of cache probe bus traffic enhancing a server’s efficiency and scalability
HyperTransport™ 3.0 Technology (HT3) Provides superior system bandwidth between CPU’s and I/O, increasing interconnect rate from 2GT/s with HT1 in previous generations up to a maximum 6.4GT/s with HT3 Helps improve overall system balance and scalability
Cache & Core Count Choice of 4 or 6-core processors, with each core having its own L1 and L2 caches, and a shared 6MB L3 cache Infrastructure designed to accommodate either single or dual socket servers providing server scalability from 4 cores to 12 cores per server platform


AMD Virtualization TM (AMD-VTM) Technology


FEATURE BENEFITS
Virtualization extensions to the x86 instruction set Enables software to more efficiently create virtual machines so that multiple operating systems and their applications can run simultaneousLy on the same computer
Tagged TLB Hardware features that facilitate efficient switching between virtual machines for better application responsiveness.
Rapid Virtualization Indexing (RVI) Helps accelerate the performance of many virtualized applications by enabling hardware-based virtual machine memory management.
AMD-V™ Extended Migration Hardware feature that helps virtualization software enable live migration of virtual machines between all available AMD Opteron™ processor generations.
I/O Virtualization Enables direct device access by a virtual machine, bypassing the hypervisor for improved application performance and improved isolation of virtual machines for increased integrity and security.

  1. Based on idle power measured at CPU socket in AMD engineering test labs using AMD internal validation platform based on 2 AMD Opteron™ processors Model 4170 HE, 2.1 GHz, with C1E feature enabled vs. disabled.
