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.

The NVIDIA Quadro2 EX/MXR Graphics Cards include the following features:

♦ 32-MB SDRAM frame buffer using 128-bit 183-MHz access
♦ AGP 4X transfers with sideband addressing
♦ 2D drawing engine
♦ 3D rendering engine
♦ 350-MHz RAMDAC
♦ 32-bit Z/stencil buffer eliminates hidden screen portions for faster loading
♦ 32-bit color for increased image quality
♦ 30-fps full-screen DVD playback
♦ Dual-monitor support with a PCI graphics card
♦ DVI monitor support (Quadro MXR only)

The NVIDIA Quadro2 MXR provides, in addition to the RGB monitor connector, a digital video
interface (DVI) connector that can directly drive a DVI monitor or another RGB monitor through
an adapter.
