The SiS Chipset Family
To provide answers to our questions, we started with a closer look at the current family of SiS chipsets. SiS provides chipset for both Intel and AMD processors that support PCI Express. Both chipsets are composed of separate North and South bridges. The SiS Intel family consists of 4 north bridges: the 649, 649FX, 656, and 656FX.
The SiS PCIe Northbridges support the PCIe x16 Graphics port, while the Southbridge supplies the remaining PCIe ports. Any of the Intel or AMD PCI Express Northbridges can be combined with one of four current SiS Southbridges that provide different feature sets. These south bridges are the 965, 965L, 966, and 966L.
The number difference reflects Audio, with the 965 supporting AC'97 and the 966 supporting High-Definition (Azalia) audio or AC'97. The "L" designates lower cost and fewer features, like native 10/100 LAN instead of Gigabit LAN, and fewer SATA ports.
