VIA has already started sampling its PT890, mass production of this chip is planned in June. Another chipset that has started sampling is the VIA K8T890 which supports PCI Express. The K8T890 is planned for Q3 2004. Both chipsets are suitable for Athlon 64 and Opterons.
The K8T890 supports 1GHz Hypertransport, giving 1GHz DDR 16-bit full duplex amounting to 2GT/second. The Via P4 chipset supports 800MHz system buses, dual 64-bit channels, DDR2/DDR1, PCI-Express and AGP 8X, and an Ultra V Link.
