Radeon Xpress 200P, Radeon Xpress 200
Most people know that a P following the chipset name indicates a desktop product in Intel's nomenclature. ATi mimics Intel in this regard as its Radeon Xpress 200P doesn't have a graphics processor, while the other chipset, the Radeon Xpress 200, does. Adding the letter G would not have made much sense, since Radeon is already well known as a graphics brand.
In addition to the broad audience ATi is able to address with the new chipset line, the manufacturer claims to offer the most cost-effective PCI Express solution for mainstream computing. This is certainly true when compared to Nvidia's nForce4 . Brimmed with features such as integrated Gigabit Ethernet including unique hardware firewall features, ATi will easily be in a position to undersell the competitor.
The pricing difference between Radeon Xpress 200P and the VIA K8T890 might be negligible, as the feature sets are equal to a large extent.
Network adapter cards for PCI Express are becoming available.
