Ati 128 Pro Agp Video Card Specifications

The ATI 128 Pro — officially known as the ATI Rage 128 Pro — is a graphics processor unit, or video card, from ATI Technologies, which is a subsidiary of semiconductor manufacturer Advanced Micro Devices. Released in 1999 when ATI was an independent company, it’s a more advanced version of the original Rage 128. Although ATI/AMD no longer produces the video card, other manufacturers still do by replicating its specifications.


ATI manufactured the ATI 128 Pro video card for connection to the Accelerated Graphics Port of desktop personal computers. The AGP could have a 2X speed, which translates into a transfer rate of 533MB per second; or 4X, which is 1,066MB per second. Some of the later iterations, however, are designed for the computer’s Peripheral Component Interconnect instead.

Video Output, Playback

Each ATI Rage 128 Pro GPU has a VGA connector. A standard used since 1987 — when technology company IBM debuted its third generation of personal computers called the IBM PS/2 — it provides the analog signals necessary for screen displays. The Rage 128 Pro uses the MPEG-2 standard for video playback, particularly for DVDs.


The standard resolution that the ATI Rage 128 Pro video card supports is Super VGA 1,920 by 1,440 pixels, with a 16.7-million color display in 32-bit depth. There’s support also for Widescreen Ultra eXtended Graphics Array’s 1,920 by 1,200 pixels, which is designed for widescreen monitors. Although the GPU is primarily designed as a 2-D graphics processor, it supports resolutions of 1,600 by 1,200 pixels and 1,280 by 1,024 pixels in 3-D mode.

Memory and Technologies

The ATI 128 Pro video card shares some of the computer’s system memory — 128MB to be exact — for its video capabilities. The system memory, however, must be based on SDRAM architecture. The Rage 128 Pro uses the DirectX application programming interface for implementing 3-D graphics effects.
