Technology Description:

The technology of the Presario notebooks utilizes a 128-bit memory bus (between the graphics memory and controller) as opposed to many notebooks which use 64-bit buses. As a result, performance levels are greatly improved over previous graphics accelerators. 128-Bit Graphics Acceleration with 1.1MB integrated video memory, used in the 1200 series, supports 64K colors in 800x600 mode, and MPEG-1. 128-Bit Graphics Acceleration with 2MB integrated video memory, used in the 1600 series, provides two times the data bandwidth over previous 64-bit controllers, supports 24-bit color (16M colors) in 800x600 mode, has two megabytes of internal video RAM, and supports MPEG-1. The faster frame buffer access in both models greatly improves MPEG, DirectDraw, and Direct 3D.

User Benefits:

Low Power Consumption

By integrating video memory onto the graphics board, power-consuming I/O pins used as connectors between the once separate chips are eliminated. Ultra high-speed and efficient transport of data to the frame buffer reduces CPU load and subsequently also reduces power consumption. Combined with other advanced power management techniques, this technology can reduce as much as one-quarter of the power used by conventional accelerators, greatly extending battery life when computing on the road.

Integrated Video Memory

Convenient chip integration places video memory on the graphics accelerator saving precious space within the portable.
