    • Increased data queue sizes
    • Coherency for 8-cores

AMD Wide Floating Point Accelerator

  • Shared FP Scheduler
  • Dual 128-bit Floating point engines – capable of teaming together for 256-bit AVX instructions or operating separately with each core.

HyperTransport™ Technology

  • One 16-bit link at up to 5600MT/s
  • Up to 8.0GB/s HyperTransport™ I/O bandwidth; Up to 16GB/s in HyperTransport Generation 3.0 mode
  • Up to 37GB/s total delivered processor-to-system bandwidth (HyperTransport bus + memory bus)

Benefit: Quick access times to system I/O for better performance.

Integrated DRAM Controller with AMD Memory Optimizer Technology

  • A high-bandwidth, low-latency integrated memory controller
  • Supports up to DDR3-18662
  • Supports new low voltage memories of 1.35V and 1.2V
  • Up to 29.9GB/s memory bandwidth for DDR3
  • New Pre-Fetcher improvements
  • Direct communications to each core in Dual-Core module (APIC registers in each core)

Benefit: Optimized memory controller to feed more cores

AMD Virtualization™ (AMD-V™) Technology with IOMMU

  • Silicon feature-set enhancements designed to improve the performance, reliability, and security of existing and future virtualization environments by allowing virtualized applications with direct and rapid access to their allocated memory.
  • IOMMU is an extension to AMD64 architecture to support address translation and access protection on DMA transfers
    • Security for User Level application and Virtual Machine guest operating system
      • Address translation and access control
      • Device isolation
      • Device assignment in virtualized systems
      • Security & trusted boot support
      • Unified interrupt management

Benefit: Helps virtualization software to run more securely and efficiently enabling a better experience when dealing with virtual systems

AMD PowerNow!™ Technology (Cool’n’Quiet™ Technology)

  • Enhanced power management features which automatically and instantaneously adjusts performance states and features based on processor performance requirements
  • C6 power state for cache flush, and voltage down individual core
  • CC6 power state allows all cores in C6 to power even lower
    • For quieter operation and reduced power requirements
  • Separate memory controller power control
  • IO-based c-state interface
  • Works automatically without the need for drivers or BIOS enablement.
  • Power can be switched on or off within a single clock cycle, saving energy with no impact to performance.

Benefit: Helps users get more efficient performance by dynamically activating or turning off parts of the processor.
