S3 Graphics Chrome 400 Series Graphics ProcessorsThe new S3 Graphics Chrome 400 Series brings the latest DirectX®10.1 graphics, Blu-ray™ and HD-DVD™ support to energy-efficient desktop and notebook platforms. Designed to provide the latest gaming experience coupled with outstanding HD content playback, S3 Graphics Chrome 400 Series graphics processors brings the highest performance-per-watt ratio ever to a new breed of energy-efficient desktop systems and portable notebook PCs. Products requiring extreme power-efficiency and rigidly low thermal specifications will now be able to take advantage of the latest graphics engine with a discrete graphics solution that supports DirectX®10.1 and PCI Express®2.0 bus technology. Offering improved 3D gaming image and texture rendering the Chrome 400 Series delivers superb gaming performance while staying cool under the hood. Microsoft® DirectX™ 10.1 Ready Shader Model 4.1 OpenGL 2.1 Programmable Unified Shader Architecture 64-bit Memory Interface AcceleRAM™ Graphics Memory Support ChromotionHD™ 2.0 Video Engine for Blu-ray™ / HD-DVD Playback H.264 Hardware Acceleration VC1 and MPEG-2 AES 128 Dual-Link DVI™ and HDMI™ with HDCP™ Advanced Power Management

S3 Chrome 400 Series Highlights Microsoft® DirectX® 10.1 Support: An S3 proprietary unified shader architecture supports the latest additions to DirectX® 10.1. Realistic 3D rendering and increased visual acuity through improved Anti-aliasing (AA), Image/Texture improvements, higher precision formats, and programmable lighting effects allow users to experience life-like rendering and image quality in supported DirectX® 10.1 applications. S3 Graphics PowerWise™ Technology:  Sophisticated algorithms and power control mechanisms will allow Chrome 400 Series GPUs to deliver the optimal balance between performance and power on-the-fly, to meet performance and application requirements for power efficient graphics intensive computing on thin and light notebook PCs and small form factor and power-efficient desktop PCs. ChromotionHD™ Video Technology: Featuring a fully programmable video architecture with true HD quality 1080p playback for Blu-ray™ and HD-DVD™ content, the ChromotionHD™ engine supports the latest HD standards including H.264, MPEG-2, MPEG-4, VC-1, WMV-HD, and AVS, for a stunning movie experience. PCI Express®2.0: Chrome 400 Series GPUs support the latest, high throughput PCI Express® 2.0 bus technology. The faster connection speed also allows users to take advantage of additional S3 Graphics technologies such as AcceleRAM™ which leverages system memory for image data storage, and MultiChrome™ Multi-GPU technology to unleash higher 3D rendering performance. Advanced Display Connectivity:  Integrated digital display support with HDCP content protection will allow users to connect to a multitude of monitors and displays for HD content viewing across a secure display path. Built-in HDMI transmitters with HD Audio controllers allow seamless HDMI connectivity, without requiring external cable connectors for audio inputs into the GPU. Display interfaces include HDMI, dual-link DVI, DisplayPort, HDTV, and VGA. AcceleRAM™: Chrome 400 Series GPUs allow users to dynamically manage the total video memory size by using a combination of local and system memory. Data transfers between system memory and the graphics processor take place on-the-fly across the PCIe bus. Advanced Display and Audio Integration: Chrome 400 Series processors incorporate two dual-link DVI transmitters each with integrated HDMI and HDCP, an integrated dual channel LVDS transmitter, an integrated TV/HDTV encoder, and support for two analog CRTs. Chrome 400 Series processors also introduce S3 Graphics’ new integrated HD Audio controller and codec. DisplayPort is supported through an external transmitter. Advanced power management: Chrome 400 Series processors support advanced power management technologies for desktop and mobile implementations, including dynamic clock controls and integrated temperature sensor technology. Individual execution units can also be turned-off when idle which allows additional power savings. Chrome 400 Series products support PCIe ASPM whielps minimize power consumption dynamically.

不知道视频解码能力与ATI相比怎么样。。期待测试。

Edison

视频解码能力应该和RV6XX不相伯仲，但是这个系列基本上和3D玩家无缘。

太好了，终于给大家多一个选择:whistling:

用于mobile或低功耗平台前景一定不错。

Edison

刚才看漏了，这个东西不支持VC-1 VLD，所以在解码特性上它很奇怪。

vp

VC-1 VLD微软根本就没有公开的硬件解码接口，所以NV和S3都不支持。至于ATI，多半是因为它和MS的特殊关系，在VC-1上得到了特殊的照顾。

硬件解码接口是由厂商公布的，与微软无关。

vp

解码接口根本不是厂商公布的，而是微软定义的。否则你怎么可能用微软定义的几个函数查询得到硬件支持解码的级别。至于PowerDVD, WinDVD之类强势ISV会和IHV进行一定程度上的合作，定义私有接口，不过这些接口也仅限于特定ISV的特定软件可以使用，没有任何通用性。真正通用的DXVA接口中没有VC1 VLD级别的接口。

硬解可以无视

最佳看片卡诞生了 :whistling:

硬件接口根本你不是你说的DXVA，它是IHV内部定义的，提供给ISV调用，例如XP下DXVA没有h264/avc、VC-1的定义，这个时候就需要ISV把这些接口（其实是驱动里的一个flag）写到解码器来调用。

DXVA2中就有VC-1 VLD的API接口，但是需要Vista。

总之短期内不用期待NV和S3会实现所谓的DXVA2的VC-1 VLD支持，除非微软又有新想法了。

NVIDIA G98支持VC-1 VLD，现有的软件都能提供支持。

為什麼那麼有自信Chrome400的類比會做得和S27一樣好？

zajara

估计又是市场上非常稀有的东东

干脆把它整合到主板里面算了~
