Southbridge of the VIA K8T800 chipset with integrated SATA controller

A chip solution form Nvidia with the CK8 chipset

Nvidia: nForce-3 Bug

The extremely low AGP performance of the NForce3 can be clearly attributed to problems with the HyperTransport channel interface to the Northbridge. That is proven by the benchmark results and the performance differences of up to 33.2 percent. Details about this can be found in the benchmark section of this article.

Originally, Nvidia had planned to also integrate a SATA RAID controller in the Southbridge. Although the controller is included in the current NForce 3, Nvidia deactivated this feature. The reason was that error-free operation was not possible. For this reason, we decided to use additional boards based on the VIA K8T800 chipset.

Nvidia (Athlon 64 FX, or alternatively GeForce FX - related names) may be a more high-profile partner for AMD than VIA. However, we would point out that VIA, with the K8T800 chipset, currently offers a clearly better solution for the Athlon 64.
