AMD FX Processors

AMD FX 8-Core Processors

• The industry’s first and only native 8-core desktop processor for unmatched multitasking and pure core performance with all-new “Bulldozer” architecture.
• New 32 nanometer die shrink designed to reduce leakage for improved efficiency, increased clock rate headroom and better thermals.

AMD Turbo CORE Technology

• The AMD FX Processors come equipped with AMD Turbo CORE Technology. AMD Turbo CORE Technology is a performance boosting technology that helps increase performance on the applications that need it the most.

New Instruction Capabilities

• AVX 
  • Advanced Vector Extensions increase parallelism tailored for scientific and 3D applications that use heavy floating point calculations
• FMA4 and XOP
  • Floating Point Vector Multiply -Accumulate  improves throughput and performance on many vector functions (integer and floating point)
• AES
  • Advanced Encryption Standard noticeably increase performance on the latest encryption applications like TrueCrypt and benchmarks like PCMark

AMD Balanced Smart Cache

• Shared L3 cache ( up to 8MB) 
  • Improved scheduling and pre-fetch capabilities
  • 64-ways (16-ways/sub-cache)
  • 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)

Integrated DRAM Controller with AMD Memory Optimizer Technology

• A high-bandwidth, low-latency integrated memory controller 
• Supports up to DDR3-1866
• 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)

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

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.
