VIA Announces VIA PT890 Chipset For Windows Vista

VIA Technologies today announced the VIA PT890 chipset ready for Microsoft Windows Vista.

The VIA PT890 supports Intel processors with up to 1066MHz FSB, DDR2 memory. The company suggests either an S3 Graphics Chrome S25 or Chrome S27 graphics card featuring DirectX 9.0 and the Chromotion 3.0 Video Engine for the "full Windows Vista Premium experience".

Utilizing the 533MB/s VIA V-Link interface, the VIA PT890 connects to the latest VIA South Bridge solutions such as the VIA VT8237A, with its integrated VIA Vinyl Multichannel Audio Suite (32-bit/192kHz). And the VIA Advanced Connectivity Suite offers a wide range of connectivity options, including support for up to eight USB 2.0 ports and 10/100 Mb/s Fast Ethernet.

The VIA PT890 also features VIA's proprietary StepUp memory technology to provide support for both DDR and DDR2 memory standards on the same motherboard.

The new chipset includes support for x16 PCI Express connectivity, delivering up to 4GB/s of dedicated graphics bandwidth per direction. The VIA PT890 also features additional x1 PCI Express peripheral support, providing 250MB/s per direction bandwidth to peripheral devices such as Gigabit Ethernet and HDTV tuner cards.

The VIA PT890 is part of VIA's Modular Architecture Platform (V-Map) strategy, which minimizes time-to-market for motherboard partners through a flexible, pin-compatible design approach for VIA core-logic solutions.

The VIA PT890 chipset is available now.
