北桥芯片负责与CPU的联系并控制内存(于Intel除Core系列以外的cpu，AMD系列cpu在K8系列以后就在cpu中集成了内存控制器，
二三极管回收、内存卡收购、肖特基二极管回收、单片机收购、NPN晶体管收购,显卡回收、
收购网卡、回
因此AMD平台的北桥芯片不控制内存)、AGP数据在北桥内部传输，提供对CPU的类型和主频、系统的前端总线频率、
内存的类型（SDRAM，DDRSDRAM以及RDRAM等等）和Zui大容量、AGP插槽、ECC纠错等支持，整合型芯片组的北桥芯片还集成了图形处理器。
区分编辑
1、南桥和北桥芯片主要区别
南桥主要是负责IO，北桥用于CPU和内存、显卡、PCI交换数据。
2、如何巧妙辨别南桥和北桥芯片？
