Performance  ​ ​ ​ ​Feature Function Benefit 
Next generation modular core architecture 

Optimized performance per watt:

  • High frequency and low-power design
  • Virtualization enhancements
  • Shared double-sized Flex FP
  • IPC enhancements

The new processor core can help enhance power efficiency for server products:

  • Help minimize cooling solution complexities.
  • Help reduce power at low utilization.
  • Enable more control for IT managers.
AMD Turbo CORE TechnologyTurns unused TDP headroom into added clock speed for improved performance.The industry's best full-core boost1 with up to a 300MHz frequency increase2.
Flex FPThe world's only flexible 256-bit FPU. Two 128-bit FMACs shared per module, allowing for dedicated 128-bit execution per core or shared 256-bit execution per module.Enhances flexibility and performance in technical computing.
High DDR3 FrequenciesDDR3-1866 MHz supportOutstanding performance for memory intensive applications
AMDP2.0 ​ ​ ​ ​ ​ ​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) in:

  • 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  effectively monitor power and thermals to optimize cooling solutions in an IT datacenter
TDP Power Cap Allows the user to set the maximum processor power ceiling via BIOS or APML. 

This technology gives enterprises the ability to customize their chips to meet power and workload demands, providing: 

  • More control over power settings
  • Flexibility to set power limits without capping CPU frequencies
AMD CoolSpeed Technology Protects processor integrity by reducing power-states, when a temperature limit is reached. 
  • Server can automatically drop into lower power mode 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 Reduces memory controller and HyperTransport™ technology links' power. 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. 
C6 Support Core power gating: When a core is halted its context is exported to system memory and voltage is removed from the core. Helps reduce power consumption at idle to minimize energy consumption when servers are not in use. 
LV-DDR3Support Supports 1.25V and 1.35V DDR3 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  ​ ​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 CPUs and I/O, increasing interconnect rate up to a maximum 6.4GT/s with HT3. Helps improve overall system balance and scalability. 
Cache and Core Count Integration of up to 8 cores within the same package, 1MB L2 cache per core (up to 8MB of L2 cache per socket), and a shared 8MB L3 cache per socket. Offers outstanding performance and performance/watt  for multi-threaded environments like virtualization, database and web serving.
