nForce2: An Overview Of Features
Before we look in detail at the individual features of the nForce2 and compare them to the established chipsets, let's look at a summary of its specs.
Northbridge: IGP And SPP Compared

Apart from new aspects of the technology, one of the most important differences from its predecessor is in the Northbridge. While the IGP (Integrated Graphics Processor) of the first nForce has always been equipped with integrated graphics, the customer can now opt for an nForce2 withouth integrated graphics, namely, the System Platform Processsor (SPP) . The SPP is a "pure" version of the Northbridge, without graphics, and therefore significantly lower in price.
