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 Technology1: 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 Capable2: 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.
Native HDMI for home entertainment: The new HDMI interface delivers true HD quality for home electronic device and PC products via a single cable. Enjoy the latest audio technologies with 7.1 digital surround sound support.
