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 gameplay

64-bit floating point texture filtering and blending
Based on the OpenEXR technology from Industrial Light & Magic (http://www.openexr.com/), NVIDIA’s 64-bit texture implementation sets new standards for image clarity and quality through floating point capabilities in filtering, texturing, and high dynamic-range (HDR) lighting.
