Features
PCI Express support
- Designed to run perfectly with the next-generation PCI Express bus architecture. This new bus doubles the bandwidth of AGP 8X delivering over 4 GB/sec in both upstream and downstream data transfers.
Dual-Link DVI
- Supports hardwares with awe-inspiring 2560-by-1600 resolution, such as the 30-inch HD LCD Display, with massive load of pixels, requiring a graphics card with dual-link DVI connectivity.
HDCP Capable
- Allows playback of HD DVD, Blu-ray Disc, and other protected content at full HD resolutions with integrated High-bandwidth Digital Content Protection (HDCP) support. (Requires other compatible components that are also HDCP capable. The HDCP function is available on PX8500 GT w/ HDCP configurations. Find the information on retail package.)
NVIDIA PureVideo HD technology
- The combination of high-definition video processors and NVIDIA DVD decoder software delivers unprecedented picture clarity, smooth video, accurate color, and precise image scaling for all video content to turn your PC into a high-end home theater. (Feature requires supported video software. The HDCP function is available on PX8500 GT w/ HDCP configurations. Find the information on retail package.)
NVIDIA SLI technology
- Delivers up to 2x the performance of a single GPU configuration for unparalleled gaming experiences by allowing two graphics cards to run in parallel. The must-have feature for performance PCI Express graphics, SLI dramatically scales performance on over 60 top PC games.
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.
Dual 400MHz RAMDACs
- Blazing-fast RAMDACs support dual QXGA displays with ultra-high, ergonomic refresh rates up to 2048x1536 85Hz.
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.
Microsoft DirectX 10 Shader Model 4.0 Support
- The standard for today's PCs and next-generation consoles enables stunning and complex effects for cinematic realism.
High dynamic-range (HDR) Rendering Support
- The ultimate lighting effects bring environments to life for a truly immersive, ultra-realistic experience.
Integrated HDTV encoder
- Provides world-class TV-out functionality up to 1080P resolution.
