Xpress 3200

The Xpress 3200 is a new revision of the Xpress 200 computer chipset released by ATI. The chipset supports AMD64 processors of the Socket 939 and also of the Socket AM2.

History of the Xpress 3200 chipset

The Radeon Xpress chipset was designed by ATI to enter the realm of the desktop arena, especially the AMD Socket 939 platform where ATI's rival, Nvidia, had a clear market advantage. The Xpress 200 was launched with the Crossfire edition of the chipset considered as the high end of the chipset. However, rolling delays with the Crossfire Master Cards forced ATI to launch the Socket 939 platform whilst the Intel platform was scrapped due to time constraints. Reviews painted the Xpress 200 Crossfire as a board that could match Nvidia's nForce 4 SLI. With the release of the nForce 4 16x SLI, ATI changed strategy and announced the RD580 chipset.

The RD580 was no different with the Xpress 200 chipset with the exception of the 40 PCI Express lanes within the Northbridge. It was claimed by ATI that having 2 chipsets with 20 PCI Express lanes would slow down data transfers when the chipset is working with multi-GPU configurations. Having just all the PCI Express lanes within the Northbridge claimed to be more efficient and less bottlenecking as compared to the nForce 4 16x SLI. The RD580 was called the Radeon Xpress 3200 and was released on March 1, 2006. Supposedly, the chipset is also configured for the new Socket AM2 and of such, many motherboard manufacturers have decided to skip the Socket 939 RD580 and began R&D on the Socket AM2 RD580.
