Southbridge: MCP And MCP-T
MCP is NVIDIA's acronym for Media and Communications Processor. The "T" version simply means "Turbo," which in this case does not translate to higher speeds, but to a more extensive range of functions.

Basically, the new MCP-T differs from the MCP in three aspects: the MCP-T offers an integrated FireWire controller and a second network controller, as well as NVIDIA's Audio Processing Unit (APU). And be careful to note that MCP has different meanings with the nForce and the nForce2. With the first nForce, the APU was included in the simple MCP, whereas with the nForce2, the MCP-T is required.
