VIA ProSavageDDR PN266T

The VIA ProSavageDDR PN266T chipset brings ultra fast DDR SDRAM memory to mobile systems based on the Intel® Pentium® III Processor-M and VIA C3™ mobile processors for the first time, smashing the performance ceiling imposed by PC133 SDRAM. In addition to better performance, DDR SDRAM also lowers memory subsystem power consumption by more than 30%, extending battery life and reducing heat dissipation enabling professional performance in svelte and stylish designs. Combined with the proven performance of the cost efficient, space saving S3 Graphics ProSavage8™ 2D/3D engine integrated into the chipset North Bridge, the VIA ProSavageDDR PN266T yields the most powerful professional mobile systems ever produced at highly competitive price points.

The VIA ProSavageDDR PN266T 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 DVD Motion Compensation is optimized for use with the Microsoft Windows® XP operating system and drives integrated graphics in mobile systems to a new level. Shared Memory Architecture (SMA) enables the PN266T 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. Integrated graphics also offers lower system power consumption by eliminating the separate frame buffer memory, and saves real estate on the mainboard enabling thinner lighter form factors. In addition, employing low voltage DDR266 SDRAM with Intel® Speedstep™ Technology lowers system power consumption augmenting the performance increase with extended battery life and usability.

The VIA ProSavageDDR PN266T 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 PN266T 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.
