NVIDIA unified architecture
Fully unified shader core dynamically allocates processing power to geometry, vertex, physics, or pixel shading operations, delivering up to 2x the gaming performance of prior generation GPUs.
Full Microsoft DirectX 10 Support
DirectX 10 GPU with full Shader Model 4.0 support delivers unparalleled levels of graphics realism and film-quality effects.
Quad NVIDIA SLI® Technology
Industry leading Quad NVIDIA SLI technology offers amazing performance scaling by implementing 4-way AFR (Alternate Frame Rendering), for the world’s fastest gaming solution under Windows Vista with solid, state-of-the-art drivers.
NVIDIA HybridPower™ Technology
HybridPower technology automatically switches from the GeForce 9800 GX2 graphics card to the motherboard GeForce GPU when running non graphically-intensive applications for a silent, low power PC experience.
PCI Express® 2.0 Support
Designed to run perfectly with the new PCI Express 2.0 bus architecture, offering a future-proofing bridge to tomorrow's most bandwidth-hungry games and 3D applications by maximizing the 5GT/s PCI Express 2.0 bandwidth (twice that of first generation PCI Express). PCI Express 2.0 products are fully backwards compatible with existing PCI Express motherboards for the broadest support.
GigaThread™ Technology
Massively multi-threaded architecture supports thousands of independent, simultaneous threads, providing extreme processing efficiency in advanced, next generation shader programs.
NVIDIA Lumenex™ Engine
Delivers stunning image quality and floating point accuracy with ultra-fast frame rates.
- 16x Anti-aliasing Technology: Lightning fast, high-quality anti-aliasing at up to 16x sample rates obliterates jagged edges.
- 128-bit floating point High Dynamic-Range (HDR) Lighting: Twice the precision of prior generations for incredibly realistic lighting effects—now with support for anti-aliasing.
NVIDIA Quantum Effects™ Technology
Advanced shader processors architected for physics computation enable a new level of physics effects to be simulated and rendered on the GPU—all while freeing the CPU to run the game engine and artificial intelligence (AI).
NVIDIA ForceWare® Unified Driver Architecture (UDA)
Delivers a proven record of compatibility, reliability, and stability with the widest range of games and applications. ForceWare provides the best out-of-box experience for every user and delivers continuous performance and feature updates over the life of NVIDIA GeForce GPUs.
OpenGL® 2.1 Optimizations and Support
Ensures top-notch compatibility and performance for OpenGL applications.
Dual 400MHz RAMDACs
Blazing-fast RAMDACs support dual QXGA displays with ultra-high, ergonomic refresh rates–up to 2048x1536@85Hz.
Dual Dual-link DVI Support
Able to drive the industry’s largest and highest resolution flat-panel displays up to 2560x1600 and with support for High-bandwidth Digital Content Protection (HDCP).
HDMI® Output
Integrated HDMI connector enables sending both high-definition video and audio signals to an HDTV via a single cable.
NVIDIA PureVideo® HD Technology
The combination of high-definition video decode acceleration and post-processing that delivers unprecedented picture clarity, smooth video, accurate color, and precise image scaling for movies and video.
- Discrete, Programmable Video Processor: NVIDIA PureVideo is a discrete programmable processing core in NVIDIA GPUs that provides superb picture quality and ultra-smooth movies with 100% offload of H.264 video decoding from the CPU and significantly reduced power consumption.
- Hardware Decode Acceleration: Provides ultra-smooth playback of H.264, VC-1, WMV and MPEG-2 HD and SD movies.
- Dual Stream Hardware acceleration: Supports picture-in picture content for the ultimate interactive Blu-ray and HD DVD movie experience.
- Dynamic Contrast Enhancement: Provides post-processing and optimization of High Definition movies on a scene by scene basis for spectacular picture clarity.
- HDCP Capable
- Designed to meet the output protection management (HDCP) and security specifications of the Blu-ray Disc and HD DVD formats, allowing the playback of encrypted movie content on PCs when connected to HDCP-compliant displays.
- Advanced Spatial-Temporal De-Interlacing: Sharpens HD and standard definition interlaced content on progressive displays, delivering a crisp, clear picture that rivals high-end home-theater systems.
- High-Quality Scaling: Enlarges lower resolution movies and videos to HDTV resolutions, while maintaining a clear, clean image. Also provides downscaling of videos, including high-definition, while preserving image detail.
- Inverse Telecine (3:2 and 2:2 Pulldown Correction): Recovers original film images from filmsconverted-to-video (DVDs, 1080i HD content), providing more accurate movie playback and superior picture quality.
- Bad Edit Correction: When videos are edited, the edits can disrupt the normal 3:2 or 2:2 pulldown cadence. PureVideo uses advanced processing techniques to detect poor edits, recover the original content, and display perfect picture detail frame after frame for smooth, natural looking video.
- Noise Reduction: Improves movie image quality by removing unwanted artifacts.
- Edge Enhancement: Sharpens movie images by providing higher contrast around lines and objects.
