​

Microsoft® DirectX® 8.X & OpenGL® 1.3 Optimizations and Support​

Delivers the best performance and guarantees compatibility with all current and future 3D applications andgames.​

Integrated TV Encoder​

Provides best-of-class TV-out functionality for resolutions up to 1024x768.​

AGP 8X​

Provides double the bandwidth of AGP 4X--2.1GB/sec. vs. 1.1GB/sec. AGP 8X enables more complex models and detailed textures, creating richer and more lifelike environments. Uninterrupted data flow allows for smoother video streaming and faster, more seamless game play.​

350MHz RAMDACs​

Supports QXGA displays with ergonomic refresh rates.​

Lightspeed Memory Architecture II​

LMA II boosts effective memory bandwidth by up to 300%. Radical new technologies_including Z-occlusion culling, fast Z-clear, and auto pre-charge_effectively multiply the memory bandwidth to ensure fluid frame rates for the latest 3D and 2D games and applications.​

The Accuview Antialiasing subsystem with advanced multisampling hardware delivers full-scene antialiased quality at performance levels never before seen.​

Video Processing Engine (VPE)​

Integrated high-definition Video Processing Engine delivers the highest quality DVD, video, and display output available in the market today. Integrated hardware MPEG2 decoder reduces CPU utilization for DVD playback to provide a longer viewing experience.​

Lossless Z-Compression​

LMA II contains a lossless form of Z-compression that delivers a 4:1 benefit. Compression is a crucial technique in saving memory bandwidth for higher performance.​

MX Memory Crossbar​

Dual memory controllers allow more efficient utilization of memory bandwidth.​

Quad Cache​

LMA II contains a caching system for primitives, vertices, textures and pixels. These caches are individually dedicated and optimized for almost instant graphics pipeline access and reuse.​

64MB 128-bit DDR Frame Buffer Memory​

Delivers up to 8.8GB per second of memory bandwidth to ensure peak performance and the smoothest frame rates.​

Integrated Dual-Channel TMDS Transmitter​

Enables two independent Digital Flat Panel (DFP) displays at resolutions up to 1280 x1024.


espero q puedan ayudarme , muchas gracias​
