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.
GigaThread™ Technology
Massively multi-threaded architecture supports thousands of independent, simultaneous threads, providing extreme processing efficiency in advanced, next generation shader programs.
Full Microsoft® DirectX® 10 Support
World’s first DirectX 10 GPU with full Shader Model 4.0 support delivers unparalleled levels of graphics realism and film-quality effects.
NVIDIA® TurboCache™ Technology
Shares the capacity and bandwidth of dedicated video memory and dynamically available system memory for turbocharged performance and larger total graphics memory.
NVIDIA® Lumenex™ Engine
Delivers stunning image quality and floating point accuracy at ultra-fast frame rates:
16x Anti-aliasing
Lightning fast, high-quality anti-aliasing at up to 16x sample rates obliterates jagged edges.
128-bit floating point High Dynamic-Range (HDR)
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 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 and delivers continuous performance and feature updates over the life of NVIDIA GeForce® GPUs.
OpenGL® 3.1 Optimizations and Support
Ensures top-notch compatibility and performance for OpenGL applications.
NVIDIA® nView® Multi-Display Technology
Advanced technology provides the ultimate in viewing flexibility and control for multiple monitors.
PCI Express Support
Designed to run perfectly with the PCI Express bus architecture, which doubles the bandwidth of AGP 8X to deliver over 4 GB/sec. in both upstream and downstream data transfers.
Dual 400MHz RAMDACs
Blazing-fast RAMDACs support dual QXGA displays with ultra-high, ergonomic refresh rates–up to 2048x1536@85Hz.
Microsoft Windows 7 Support
Windows 7 is the next generation operating system that will mark a dramatic improvement in the way the OS takes advantage of the graphics processing unit (GPU) to provide a more compelling user experience. By taking advantage of the GPU for both graphics and computing, Windows 7 will not only make today’s PCs more visual and more interactive but also ensure that they have the speed and responsiveness customers want.
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 low CPU utilization and power.
Hardware Decode Acceleration
Provides ultra-smooth playback of H.264, VC-1, WMV and MPEG-2 HD and SD movies.
Spatial-Temporal De-Interlacing
Sharpens 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, up to 1080i, 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 films-converted-to-video, providing more accurate movie playback and superior picture quality.
Bad Edit Correction
When videos are edited after they have been converted from 24 to 25 or 30 frames, 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.
Video Color Correction
NVIDIA’s Color Correction Controls, such as Brightness, Contrast and Gamma Correction let you compensate for the different color characteristics of various RGB monitors and TVs ensuring movies are not too dark, overly bright, or washed out regardless of the video format or display type.
Noise Reduction
Improves movie image quality by removing unwanted artifacts.
Edge Enhancement
Sharpens movie images by providing higher contrast around lines and objects.
