Q: What is AGP?
A: AGP (Accelerated Graphics Port) is a new bus architecture for 3D
graphics. The AGP slot eliminates the PCI bandwidth bottleneck by
bypassing the PCI interface and accessing the system memory directly.
Currently, the AGP supports 1X and 2X modes, which yield bandwidths
of 264MB/s (at 33MHz bus speed) and 533MB/s (at 66MHz bus
speed), respectively. Compare this with the mere 132MB/s (at 33MHz
bus speed) that you get with the PCI bus.
Q: Does my operating system support AGP?
A: Currently, only Windows 98 and Windows NT 5.0 will have built-in
support for AGP. Some AGP cards require Windows 95 OSR2.1 or a
special driver from Intel. Please check with your graphics vendor for
more details.
