Chipset Features
Full Microsoft® Direct® 9.0 Shader Model 3.0 Support
The standard for today’s Purchase and next-generation consoles enables stunning and complex efects for cinematic realism. NVIDIA® GPUs offer the most complete implementation of the Shader Model 3.0 feature set – including vertex texture fetch (VTF) – to ensure top-notch compatibility and performance for all DirectX9 applications.
Ture High Dynamic-Range (HDR) Rendering Support
The ultimate lighting effects bring environments to life for a truly immersive, ultrareailstic
experience. Based on the OpenEXR technology from Industrial Light and Magic, NVIDIA’s 64-bit texture implementation delivers state-of-the-art high dynamic-range (HDR) visual effects through floating point capabilities in shading, filtering, texturing, and blending.
NVIDIA® CineFX® 4.0 Engine
Delivers advanced visual effects at unimaginable speeds. Full support for Microsoft® DirectX® 9.0 Shader Model 3.0 enables stunning and complex special effects. Next-generation shader architecture with new texture unit design streamlines texture processing for faster and smoother gameplay.
NVIDIA® SLI™ Technology
Delivers up to 2x the performance of a single GPU speeds. Full support for Microsoft® DirectX® 9.0 Shader Model 3.0 enables stunning and complex special effects. Next-generation shader architecture with new texture unit design streamlines texture processing for faster and smoother gameplay.
Adaptable Programmable Video Processor
PureVideo’s programmable technology adapts to new video encoding formats as they are developed to provide a future-proof video solution.
High-Definition H.264, MPEG-2 and WMV Hardware Acceleration
Smoothly playback H.264, MPEG-2, and W MV video including WMV HD with minimal CPU usage so the PC is free to do other work.
Advanced Spatial Temporal De-Interlacing
Smoothes video and DVD playback on progressive displays to deliver a crisp, clear picture that rivals high-end home theater systems.
High-Quality Scaling
High-quality scaling technology delivers a clear, clean image at any window size, including full-screen HDTV resolutions up to 1080p.
Video Color Correction
Corrects differences in color characteristics of RGB monitors and TV monitors through NVIDIA PureVideo’s ProcAmp Color Controls setting, such as PureVideo s ProcAmp Color Controls setting, such as ensures videos are not too dark, overly bright, or washed out regardless of the video format or display.
Integrated HDTV Encoder
Provides analog TV-output (Component/Composite/S-Video) up to 1080i resolution.
256-Bit Memory Interface
Delivers more memory bandwidth and efficiency to power the latest games and applications at blazing speeds.
NVIDIA® UltraShadow™ II Technology
Enhances the performance of bleeding-edge games, like id Software’s DOOM 3, that feature complex scenes with multiple light sources and objects.
128-Bit Studio-Precision Computation
128-bit studio-precision computation through the entire pipeline prevents image defects due to low precision and ensures the best image quality for even the most demanding applications.
Full-Speed 32-Bit Color Precision
Delivers increased image quality with no performance compromise.
NVIDIA® ForceWare® Technology
Delivers a proven record of compatibility, reliability, and stability with the widest range of games and applications. ForceWare ensures the best out-of-box experience for every user and delivers continuous performance and feature updates over the life of NVIDIA GeForce GPUs.
Looking at the specs we see that the 7900GS is based on Nvidia’s G71 90nm core (the same process technology as used in Nvidia’s mighty 7950GX2) meaning that power requirements will be at a minimum, consequently the chip will give out less heat, fairly handy for a passively cooled card I think you will agree. The stock speed for the GS core is 450MHz and MSI have stuck to this speed for the NX7900. For the memory we have 256mb of DDR3 running at the default frequency of 660MHz (1320 Effective). These are the same clocks as the GS’s bigger brother, the 7900GT, but as you can see from the image below, the 7900GS has 4 less pixel processors and one of its vertex processors disabled. Sitting 6th from top to the Nvidia throne you could class the 7900GS as being kind of in the middle of the top set of Nvidia based cards, although its a card with a difference due to its passive heatsink.
