820芯片组与CopperMine处理器的组合已经代替了BX芯片组与Katmai处理器的组合,成为英特尔公司在高端市场的主推对象。比起后一种组合,前者不仅能够支持后者所不能支持的一些主流接口规范,还提供了更高的前端总线频率和更多的功能,是追求性能的高端用户的当然选择。功能 820芯片组摒弃了传统的南北桥架构,而是采用了8XX芯片组系列独有的Hub体系。Hub体系不仅能够为I/O控制器和内存控制器之间提供266MB/s的带宽通道(PCI总线只能提供133MB/s的带宽),它的仲裁规则还允许多种功能并发运行(例如Audio、Video)。这样,PC中所传输的数据不会在总线一侧产生拥堵,使高效率的数
The combination of the 820 chipset and the CopperMine processor has taken the place of the combination of the BX chipset and the Katmai processor, becoming the main target for Intel in the high-end market. Compared with the latter combination, the former can not only support some of the mainstream interface specifications that the latter can not support, but also provide higher FSB frequency and more functions, making it an obvious choice for high-end users pursuing performance. Function 820 chipset abandoned the traditional north and south bridge architecture, but the unique 8XX chipset series Hub system. Not only does the hub system provide 266MB / s of bandwidth between the I / O controller and the memory controller (the PCI bus can only provide 133MB / s of bandwidth), its arbitration rules allow multiple functions to run concurrently (such as Audio , Video). In this way, the data transmitted in the PC will not cause congestion on the bus side, making the number of high-efficiency
