The VIA ProSavageDDR KM266 chipset offers an unbeatable combination of performance, flexibility and cost effectiveness enabling OEMs and System Integrators to develop AMD Athlon™ XP and AMD Duron™ processor based systems across the complete range of price points based on the same mainboard platform.

The VIA ProSavageDDR KM266 offers up to 2.1GB/s of memory bandwidth with its support for up to 4GB DDR266 SDRAM. This provides memory intensive applications (such as content creation, media streaming, 3D gaming, etc.) the bandwidth they need to perform optimally and increases the data throughput available to the integrated graphics core.

The S3 Graphics ProSavage8™ 2D/3D Accelerator with internal AGP 8X bandwidth and Motion Compensation is optimized for use with the Microsoft Windows® XP operating system and drives integrated graphics systems to a new level. Shared Memory Architecture (SMA) enables the ProSavageDDR KM266 to utilize the system memory for frame buffer and texture memory on an internal data path doubled to 128-bit capacity. Thus, the DDR memory subsystem, offering up to 2.1GB/s of memory bandwidth, increases the overall performance of the integrated graphics core by up to 50% over SMA chipsets based on PC133 SDRAM.

The VIA ProSavageDDR KM266 also makes use of VIA's V-Link Hub Architecture, which provides a dedicated 266MB/s bus between the north and south bridge. Less advanced chipsets use the 132MB/s PCI bus as a link, which must be shared with all PCI peripherals. VIA ProSavageDDR KM266 has a full set of networking and communication features with the exact specification depending on your choice of VIA V-MAP 8233 Series South Bridge. As standard these include Integrated 2 Channel AC'97 Audio, Integrated MC'97 Modem, Support for ATA 33/66/100 and 4 or more USB ports. Options include an integrated 3Com® networking MAC and ATA-133 Fast Drive™ depending on your design priorities.

Benefits of VIA KM266

Ultra Fast DDR Memory Performance
The high performance DDR subsystem of the VIA ProSavageDDR KM266, with up to 2.1GB/s of bandwidth offers vastly increased performance from AMD Athlon XP and AMD Duron based systems. With twice the bandwidth of PC133 SDRAM, multi tasking in the most advanced software applications is stable and fast improving productivity for end users.

Smooth DVD Playback and Gameplay
S3 Graphics ProSavage8 2D/3D technology with equivalent AGP 8X bandwidth and digital video motion compensation enables stunning quality in key applications like digital video playback alongside smooth gameplay on the latest 3D titles.
