Appendix E Compaq/NVIDIA GeForce2 GTS AGP Graphics Card

E.2 FUNCTIONAL DESCRIPTION

The NVIDIA GeForce2 GTS-SD 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.
