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.
HDCP Capable
- Designed to meet the output protection management specifications of the Blu-ray Disc and HD DVD formats, allowing the playback of encrypted movie content on PCswhen connected to HDCP-compliant displays.
Built for Microsoft Windows Vista
- NVIDIA's fourth-generation GPU architecture built for Windows Vista gives users the best possible experience with the Windows Aero 3Dgraphical user interface.
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.
