3. Advantages of AMD dual-core processor
1. Architectural Advantages
AMD Opteron processors were designed from the beginning with the addition of a second core. The two CPU cores use the same system request interface SRI, HyperTransport technology and memory controller, and are compatible with the 940-pin interface used by a 90-nanometer single-core processor. Therefore, it can be said that AMD's technical architecture has laid a solid foundation for realizing dual-core and multi-core. AMD's direct connection architecture (that is, the CPU core is directly connected to external I/O through hypertransmission technology, and does not pass through the front-end bus) and integrated memory controller technology make each core its own cache available and has its own dedicated lane direct access I/O. There is no problem of resource competition, making it easier to achieve dual-core and multi-core.
2. Smooth upgrade
AMD's dual-core CPU has the same interface specifications (pin count) and power consumption as the existing single-core CPU. Therefore, when switching from a single-core to a dual-core, there is no need to replace the chipset, motherboard, or power supply. It only needs to upgrade the BIOS software, unplug the single-core processor and plug in the dual-core processor. Chipset, motherboard, and power supply manufacturers do not need to invest in new R&D costs, and the price will naturally decrease according to the laws of the semiconductor market. Users' existing equipment can also improve performance by upgrading the CPU. Therefore, it has a very big advantage in application, that is, the power consumption remains unchanged. For high-density servers such as data centers, it has great advantages. Without the need to add additional cooling equipment, the system performance can be immediately improved and the total cost of ownership can be reduced.
3. Low power consumption
AMD's dual-core Opteron processors used in servers and workstations consume less than 95W. AMD integrates the memory controller into the processor. The memory control part does not require additional energy consumption. The reduction in processor energy consumption can also bring about energy savings in the heat dissipation of the entire machine system. Therefore, servers produced by AMD processors have greatly improved energy efficiency.
The latest AMD dual-core Opteron processor also uses AMD PowerNow!TM technology that supports optimized power management, which allows the operating system to dynamically adjust power supply according to the load of the processor, reduce power consumption costs, and increase IT ROI. Experiments show that the Opteron processor using AMD PowerNow!TM technology saves power as much as 75% when the system is idle.
4. Support from many manufacturers
Recently, AMD dual-core Opteron processor won the "2005 Best TechEd Award", which was selected by Windows IT Pro and SQL Server magazine at Microsoft's 2005 TechEd Conference. This is the two consecutive years that AMD64 Technology has won this honor at Microsoft's event for IT professionals and developers. In 2004, the AMD64 platform won the "2004 TechEd Best" award for its technological innovation in industry standard 64-bit architecture.
In terms of servers, many top domestic and foreign computer manufacturers including HP, IBM, Sun, Dawn, Cray, Supermicro, Egenera, etc. have launched systems based on AMD dual-core processors. With the joining of many OEM manufacturers, many business users, including Microsoft Technology Center (MTC), have gradually increased the deployment of enterprise-level computing platforms based on AMD's dual-core Opteron processors.
4. Summary
AMD's dual-core technology truly integrates two cores in one crystal (chip), and can communicate at high speed between cores, greatly improving computing performance. Moreover, AMD can achieve smooth upgrades from single-core to dual-core, without requiring upstream and downstream manufacturers to develop new motherboards, power supplies, fans, etc., and ultimately save money for customers. In the environment where China builds an energy-saving society, the significant energy-saving characteristics of AMD technology and products are more valuable and far-reaching.
The place where dual-core processors can best exert its effectiveness should be the server market at present. Since servers usually require high-performance computing, dual-core has obvious advantages over single-cores, so there is much more demand for dual-cores in commercial and enterprise-level computing than households. AMD's powerful computing platform is particularly popular in the field of digital content production (DCC). In China and even the world, major TV stations, animation, comic design companies, etc. all use AMD's 64-bit platform.
With its powerful performance and excellent application advantages, AMD serves 64-bit computing power in various industries around the world. Its successful application in various fields such as distance education, petroleum exploration, telecommunications, the Internet, finance, and high-performance computing further confirms the value of AMD's dual-core processor innovation.
After installing the operating system, you need to configure the server. I have prepared some commonly used software for the server for you, which are often used by everyone. There are no viruses, so please feel free to use it.http://s.
