Rage PRO
Rage Pro - was a 64-bit chip from ATI Technologies Inc. This chip supported up to 8 megabytes of SGRAM, SDRAM or EDO memory. Rage Pro had a fairly fast 2D core and supported 2D resolutions up to 1600x1200 in truecolor. The chip has a 4 kilobyte texture cache, which was designed to increase the speed of texture mapping on large surfaces.
When working with AGP, Rage Pro supported DiME, which allowed it to store textures in system memory and work with them without reloading them into local memory. The chip supported DVD and played MPEG just fine.

Among the advantages of the Rage Pro chip are high speed in 2D, as well as very good video playback quality. Among the shortcomings - low speed in 3D, poor OpenGL, problems with transparency and filtering.
