The nForce2 is the only dual-channel memory controller available in the AMD pantheon.
There are two Northbridges to choose from: one with the Integrated GeForce4 MX-class graphics (nForce2 GT) and one without (nForce2 ST). Both offer support for AGP 8x and up to DDR400 memory, although we recommend you use DDR266 or DDR333 memory in synchronous mode (DDR266 for chips with a 266MHz FSB, DDR333 for those with a 333MHz FSB) for best performance.
The nForce2's integrated graphics processor is designed to match GeForce4 MX performance. Where it may not be able compete against the likes of a card like a GeForce4 Ti4200, it can handle current 3D games at lower resolutions.
Two Southbridges are on offer for the nForce2: the MCP (Media and Communications Processor) and the MCP-T. The MCP-T is the upper-class model offering support for FireWire, dual-Ethernet and SoundStorm hardware audio support. Audio is identical to the original nForce, providing proper Dolby Digital AC-3 sound. The MCP variant, available for value motherboards, will offer support for a single network channel and standard AC'97 audio.
The HyperTransport link between the Northbridge and Southbridge also remains the same as the nForce, and allows them to exchange data at up to 800MB/s.
