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.
PCI Express Support
Designed to run perfectly with the new PCI Express bus architecture, offering a future-proofing bridge to tomorrows most bandwidth-hungry games and 3D applications by maximizing the 5 GT/s PCI Express bandwidth (twice that of first generation PCI Express). PCI Express 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 at 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® 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 Optimization 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).
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.
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.
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 & 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.
Integrated SD and HD TV Output
World-class TV-out functionality via Composite, S-Video, Component or DVI connections. Supports resolutions up to 1080i/1080p, depending on connection type and TV capability
