Hardware Updates For software requirements

Graphics hardware requirements for vista Operating System 2006
Vista's graphics requirements are defined in relation to the different desktop experiences.
Aero Glass
This graphics mode adds support for 3D graphics, animation and visual special effects in addition to the features offered by Aero Express.
Intended for mainstream and high-end graphics cards.
At least 64 MB of graphics memory, 128 MB recommended, or 256 MB for 1600x1200+.
At least 32 bits per pixel.
3D hardware acceleration with capabilities equal to DirectX 9.
A memory bandwidth of 2 GB / second.
Capable of drawing ~1.5M triangles / second, one window being ~150 triangles.
A graphics card that uses AGP 4X or PCI Express 8-lane bus.
It is likely that such a configuration will be entry-level or lower by Vista's release in 2006.
Aero Diamond A graphics mode customized for the Vista Media Center Edition, and will not be made available in the other editions. Not much information is currently available, but it appears that it will be the most advanced level of graphics in Vista, requiring hardware at the same level or greater than the Aero Glass visual style.
Aero Express
The lesser Aero visual experience offering only the basic visual improvements introduced by Vista, such as composition based DPI scaling.
Intended for mainstream or lower-end graphics cards. Uses the Avalon Desktop Composition window manager. A Vista Driver Display Model (LDDM) driver is a requirement.
Some graphics cards already support LDDM. In some Vista builds (4074, 5048), LDDM is already supported to run Aero Glass. To Go
The new Vista look & feel without any visual special effects, similar to the visual style Luna of Windows XP in that it resembles merely an application skin. As with Luna, no additional hardware requirements compared to the classic Windows interface.
A simple option for consumer upgrades, and mobile / low-cost devices. No additional requirements compared to the lesser Classic mode. Fallback mode in case the hardware requirements for Aero aren't met.
Classic
The most basic user interface offered by Vista, which is also seen in Windows 2000, or Windows XP with its visual style Luna deactivated.
An option for corporate deployments and upgrades.
Requires Windows XP Display Driver Model (XPDM) or LDDM drivers. No graphics card hardware requirements exceeding those of Windows XP
