Key Architectural Features of AMD Phenom™ X4 Quad-Core Processors

The industry's first true Quad core x86 processor

* True quad-core designed from the ground up for better communication between cores.
o 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 memory controller and I/O to the CPU.
* Designed to enable simultaneous 32- and 64-bit computing
* Integrated DDR2 Memory Controller
* BENEFITS :
o Increases application performance by reducing memory latency
o Scales memory bandwidth and performance to match compute needs
o HyperTransport™ Technology provides up to 16.0GB/s peak bandwidth per processor—reducing I/O bottlenecks
o Up to 33.1GB/s total delivered processor-to-system bandwidth (HyperTransport bus + memory bus)


AMD Balanced Smart Cache

* Shared L3 cache
* In addition to the 512K L2 cache per core, up to 2MB of L3 cache shared by up to 4 cores.
o BENEFIT : Shortened access times to 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.
o BENEFIT : Larger data paths for quicker floating point calculations and better performance.


HyperTransport™ technology

* One 16-bit link up to 4000MT/s
* Up to 8.0 GB/s HyperTransport™ I/O bandwidth; Up to 16.0GB/s in HyperTransport Generation 3.0 mode
* Up to 33.1GB/s total delivered processor-to-system bandwidth (HyperTransport bus + memory bus)
o BENEFIT : Quick access times to system resources for better performance.


Integrated DDR2 DRAM Controller with AMD Memory Optimizer Technology

* A high-bandwidth, low-latency integrated DDR2 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
* Support for 64-bit DDR2 SDRAM memory
* Up to 17.1GB/s memory bandwidth
o BENEFIT : Quick access to system memory for better performance.
