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.

nfiniteFX II Engine
The NVIDIA nfiniteFX II engine incorporates dual programmable vertex shaders, faster pixel shaders and 3D textures--giving developers the freedom to program a virtually infinite number of custom special effects to create true-to-life characters and environments. nfiniteFX II is a feature of all GeForce4 Ti GPUs; the GeForce4 4200 Go GPU; and the Quadro4 980, 900, and 750 XGL GPUs.

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 gameplay. (AGP 8X/4X compliant)

 Quadro4 XGL--Workstation Software Architecture
Quadro workstation graphics are certified by more professional applications than any other product in the industry. NVIDIA’s Unified Driver Architecture (UDA) ensures that certifications, feature enhancements and performance tuning automatically benefit past and present Quadro products, resulting in performance enhancements throughout the life of the product.
