VIA ProSavageDDR KN266: Delivering unmatched
performance and extended battery life in next
generation AMD Athlon? 4 mobile systems
Mobile systems are accounting for an increased proportion of new PC sales, with
consumers often choosing the convenience of a notebook PC in preference to a
desktop system. This trend is demanding more from mobile systems, with a balance
of desktop equivalent performance and extended battery life expected by end users.
The VIA ProSavageDDR KN266, the first mobile integrated graphics chipset with DDR
memory, enables this balance to be achieved by providing a platform for cost
effective and high performance mobile systems with extensive communication and
networking feature sets.
The launch of the VIA ProSavageDDR KN266 chipset brings ultra fast DDR SDRAM
memory to mobile systems 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 KN266 yields the most powerful professional mobile
systems ever produced at highly competitive price points.
The VIA ProSavageDDR KN266 benefits from the following key technologies:
? DDR200/266 SDRAM Support: The VIA ProSavageDDR KN266 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. As well as increasing performance DDR266 SDRAM
enables a more than 30% reduction in memory subsystem power
consumption, running at only 2.5V.
? S3 Graphics ProSavage8? Integrated Graphics core: The 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 KN266 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.
? Supports AMD PowerNow!? Version 2.0: AMD PowerNow!? technology is
a sophisticated processor power management solution, extending battery life
by up to 30% without compromising performance and enabling your notebook
to run cooler and quieter. AMD PowerNow! technology can substantially

increase battery life without a user-perceptible difference in application
performance. While running in the Automatic Mode of operation, both the
voltage and operating frequency of the CPU are dynamically controlled in
response to the system's real time demand for CPU processing power.
Whenever less processing power will do the job without user impact, AMD
PowerNow! technology lowers the CPU voltage and operating frequency,
which results in optimized battery life.
? High-Speed V-Link Hub Architecture: The VIA ProSavageDDR KN266
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.
? V-MAP: Based on the unique VIA Modular Architecture Platform (V-MAP), the
VIA ProSavageDDR KN266 provides OEMs and SIs with unparalleled flexibility
and scalability for existing and future PC designs. A choice of VT8233 series
V-link South Bridges is available on the platform with differing feature sets
enabling OEMs and SIs to target system designs at specific segments of the
marketplace without the expense of developing new mainboard platforms.
Integrated Graphics in Mobile Systems
The VIA ProSavageDDR KN266 with the S3 Graphics ProSavage8? core integrated
into the North Bridge offers significant advantages over discrete graphics solutions in
the mobile marketplace.
Integration reduces system cost: Integrated graphics allow OEMs and System
Integrators to eliminate an external graphics card from the cost of a VIA ProSavage
based system while maintaining competitive 2D and 3D performance.
ProSavage8? Graphics Performance: With effective AGP 8X, up to 32MB of
frame buffer and DVD motion compensation the ProSavage8? provides stunning
video quality and performance.
Saves Real Estate on the Mainboard: Enables thinner lighter designs with lower
power consumption due to elimination of the dedicated frame buffer memory (SMA
chipsets use the system memory for frame buffer) and the lower transistor count.
ProSavage Driver Set: S3 Graphics ProSavageDDR chipsets have a mature and
comprehensive unified driver set, minimizing compatibility issues and reducing
deployment risk for corporate customers.
Key Features include:
? 128-bit 2D/3D Graphics Accelerator
? Effective AGP 8X internal bandwidth
? 2.1GB/s transfer rate
? 8M triangles/s
? 32-bit Rendering, Bump Mapping, Vertex and Table fog
