S3 Chrome 20 Series Highlights

PCI Express™
The Chrome 20 Series employs a native PCI Express (PCIe) high speed serial link implementation. It supports 16x, 8x, 4x, and 1x lane configurations.

DirectX™ 9.0c Shader Model 2.0+ Suport
Chrome 20 Series hardware support for Microsoft’s DirectX 9.0c Vertex and Pixel Shaders version 2.0+ allows the latest games to leverage shaders as they create stunning visual effects using subtle texture blends along with complex lighting and material effects for a great gaming experience.

Flexible Memory Architecture
The flexible memory architecture allows support for modern GDDR technologies (GDDR2/GDDR1 up to 500MHz and GDDR3 up to 700MHz) in configurations of 256-32MB (GDDR3/GDDR1) and 512-64MB (GDDR2) in 128-32bit interfaces.

AcceleRAM Technology
The Chrome 20 Series can provide an optimal feature/price alternate solution to integrated graphics by allowing dynamic sharing of system main memory as part of the local video memory via the high speed PCIe bus using a smaller capacity/bit – width local video memory.

Chromotion 3.0 Programmable Video Engine
The advanced Chromotion 3.0 programmable video engine is fully compatible with Microsoft DirectX-VA media acceleration. Its powerful programmable video effects can be applied to almost all video codecs, including Windows Media Video 9-HDTM (WMV9-HD) and MPEG-2 HD. Post-processing filters enhance video from poor, low bit rate source materials. Real-time rendering capabilities bring video effect processing to mainstream home video enthusiasts, who can now exercise as much ArtisticLicense™ as advanced video artists.

HDTV Hi-Def Experience
The integrated HDTV Hi-Def encoder technology supports all 18 DTV ATSC and DVB standards, including 1080p. In HDTV Hi-Def mode, the Chrome 20 Series brings the theater experience into the home for all home entertainment PC media. Video games explode to life in vivid detail, and Hi-Def corporate presentations will set new standards.

Advanced Display Technology
This advanced technology allows the capability of supporting all the leading edge display technologies; such as CRTs, single/dual DVI monitors in single/dual link mode with or without HDCP, single/dual channel LVDS panels, TVs, and HDTVs. Displays are supported for various combinations in independent DuoViewTM modes and in DuoRotateTM modes.

Advanced Mobile Compatibility
Advanced technologies for mobile implementations make the Chrome XM20 Series especially suited to the mobile environment. ULP (Ultra Low Power) configurations enable specific low power management modes. Dynamic clock gating allows additional power saving capabilities. S3 Graphics’ LCD PanelSharp™ Expansion ensures smooth scaling.

MultiChrome™ Technology
MultiChrome is an open-platform and cable free multi-GPU acceleration technology. MultiChrome enables two Chrome S20 Series GPUs to operate together to provide additional game acceleration on any motherboard with multiple physical x16 PCI Express slots. MultiChrome is compatible with both dual x8 and dual x16 PCIe configurations.
