Appendix E Compaq/NVIDIA Quadro2 EX/MXR AGP Graphics Cards
E.2 FUNCTIONAL DESCRIPTION
The NVIDIA Quadro2 MXR Graphics Card provides high performance 2D and 3D display
imaging. The card’s AGP design provides an economical approach to 3D processing by off-
loading 3D effects such as texturing, z-buffering and alpha blending to the system memory while
32 megabytes of on-board SDRAM stores the main display image.
