AMD Opteron™ 6100 Series Processor – Features and Benefits

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
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 equate to a significant power savings in your datacenter depending on system configuration, when the Northbridge and HyperTransport™ technology links are powered down and cores are at idle.
LV-DDR3	Lower memory voltage of 1.35V vs. standard memory at 1.5V	Helps to reduce overall power consumption

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
Quad Channel Memory	Doubles the memory capacity compared to previous generations of AMD Opteron™ processors¹	Can increase performance especially in memory-intensive workloads
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	Can result in faster queries that can increase performance for cache sensitive applications such as database, virtualization, and compute intensive applications.
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 for scale out computing environments like HPC, database, and web serving
Cache & Core Count	Integration of up to 12 cores within the same package, and each core having its own L1 and L2 caches, and a shared 12MB L3 cache	Offers improved performance and performance/watt (compared to prior generations) for multithreaded environments like virtualization, database, and web serving

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.
