Server Processors AMD Opteron
The AMD Opteron server processor empowers the user’s business with world class performance levels for 1-8P x86 servers. Its key features and benefits include:
The AMD 64 platform facilitates 64 bit computing. It is designed for simultaneous 32 bit and 64 bit computing with no performance degradation. AMD’s revolutionary direct connect architecture enhances overall system performance and efficiency. This is achieved because the traditional bottlenecks get eliminated. The DCA or Direct Connect Architecture does not involve any front side buses. In fact, the processors, memory controller, and I/O are directly connected to the CPU and communicate at CPU speed. This technology is available with AMD64 processors, including the AMD Opteron™ and AMD Athlon™ 64 processors, as well as with AMD Turion™ 64 mobile technology. The Direct Connect Architecture features an integrated, on-die memory controller, optimizing memory performance and bandwidth per CPU.
The HyperTransport™ technology is a high-speed, bi-directional, low latency, point-to-point communication link that provides a scalable bandwidth interconnect between computing cores, I/O subsystems, and other chipsets. The AMD Opteron processors support up to three coherent HyperTransport links, yielding up to 24.0 GB/s peak bandwidth per processor.
Quad-Core AMD Opteron™ Processors delivers the functionality and power of multiple processors on a single quad-core design. It delivers unmatched performance, optimal virtualization, enhanced power efficiency, and low TCO — all within a consistent footprint, and power and thermal envelopes.
Quad-Core AMD Opteron™ processors with Direct Connect Architecture and AMD Virtualization™ (AMD-V™) technology offers the highest performing, flexible, and secure server virtualization solutions. Rapid Virtualization Indexing, an enhancement to AMD-V technology in Quad-Core AMD Opteron processors, is designed to dramatically increase the performance of virtualized applications while enabling faster switching between virtual machines (VMs), so you can host more VMs per server and maximize the benefits of virtualization.
The Device Exclusion Vector (DEV) – another AMD exclusive – acts like a traffic cop, controlling access to virtual machine memory based on permission, isolating virtual machines for secure operation.
Quad-Core AMD Opteron processors improve power efficiency with several key technologies. The enhanced AMD PowerNow Technology offers reduced power consumption thereby providing improved power management across all 4 cores. Dual Dynamic Power Management™ allows each processor to maximize the power-saving benefits of Enhanced AMD PowerNow! technology without compromising performance. The AMD CoolCore Technology reduces power consumption within each core. The integrated DDR2 DRAM Memory Controller facilitates low power memory in order to minimize power consumption. AMD’s Integrated Memory Controller works exclusively with high bandwidth, energy-efficient DDR2 memory. Average CPU Power or ACP values are determined by measuring processor power consumption including power for the cores, memory controller and HyperTransport™ Technology links while running precise and relevant commercially useful high utilization workloads.
The EVP or Enhanced Virus Protection feature reduces any associated costs with certain malicious viruses, worms, and Trojan horses. Users get to enjoy solid security against viruses and protect their valuable business data as well as fortify their network integrity.
