AMD Phenom™ II Key Architectural Features

AMD Phenom™ II X6 Six-Core Processors
The backbone of the VISION Black technology platform, the new AMD Phenom™ II X6 six-core processors are the fastest CPUs AMD has ever created. The AMD Phenom™ II X6 six-core processors are also the world's only six-core processors for under $200*. At the heart of a VISION Black Technology platform, the AMD Phenom II X6 processor is the most advanced AMD desktop processor and features innovative AMD Turbo CORE technology to adjust to the dynamic needs of performance users.


New AMD Turbo CORE Technology
Both the AMD Phenom™ II X6 1055T and 1090T come equipped with AMD's new Turbo CORE technology. AMD Turbo CORE technology is a performance boosting technology that automatically switches from six cores to three turbocharged core for applications that just need raw speed over multiple cores. While in Turbo CORE mode, the AMD Phenom™ II X6 1090T shifts frequency speed from 3.2GHz on six cores, to 3.6GHz on three cores, making it the fastest processor AMD has ever created.

AMD Phenom™ II Triple and Quad-Core Processors
- True quad-core and triple-core designed from the ground up for better communication between cores.
Benefit: Cores can communicate on die rather than on package for better performance

AMD64 with Direct Connect Architecture
- Helps improve system performance and efficiency by directly connecting the processors, the memory controller, and the I/O to the CPU.
- Designed to enable simultaneous 32- and 64-bit computing
- Integrated Memory Controller
Benefits: Increases application performance by dramatically reducing memory latency
Scales memory bandwidth and performance to match compute needs
HyperTransport™ Technology provides up to 16.0GB/s peak bandwidth per processor—reducing I/O bottlenecks
Up to 37GB/s total delivered processor-to-system bandwidth (HyperTransport bus + memory bus)

AMD Balanced Smart Cache
- Shared L3 cache (either 6MB or 4MB)
- 512K L2 cache per core
Benefit: Shortened access times to the highly accessed data for better performance.

AMD Wide Floating Point Accelerator
- 128-bit floating point unit (FPU)
- High performance (128bit internal data path) floating point unit per core.
Benefit: Larger data paths and quicker floating point calculations for better performance.

HyperTransport™ Technology
- One 16-bit link at up to 4000MT/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 PC2-8500 (DDR2-1066); PC2-6400 (DDR2-800), PC2-5300 (DDR2-667), PC2-4200 (DDR2-533) or PC2-3200 (DDR2-400) SDRAM unbuffered DIMMs – AM2+
- Support for unregistered DIMMs up to PC2 8500(DDR2-1066MHz) and PC3 10600 (DDR3-1333MHz) – AM3
- Up to 17.1GB/s memory bandwidth for DDR2 and up to 21GB/s memory bandwidth for DDR3
Benefit: Quick access to system memory for better performance.

AMD Virtualization™ (AMD-V™) Technology With Rapid Virtualization Indexing
- 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.
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
- For quieter operation and reduced power requirements
Benefit: Enables cooler and quieter platform designs by providing extremely efficient performance and energy usage.

AMD CoolCore™ Technology
- Reduces processor energy consumption by turning off unused parts of the processor. For example, the memory controller can turn off the write logic when reading from memory, helping reduce system power.
- 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.

Dual Dynamic Power Management™
- Enables more granular power management capabilities to reduce processor energy consumption.
- Separate power planes for cores and memory controller, for optimum power consumption and performance, creating more opportunities for power savings within the cores and memory controller.
Benefit: Helps improve platform efficiency by providing on demand memory performance while still allowing for decreased system power consumption
