Features & Specifications

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 CPU 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)
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.
