3D RAGE II (II+,II+DVD, IIc)
The second generation Rage (aka Mach64 GT-B) offered roughly two times greater 3D performance. Its graphics processor was based again on a re-engineered Mach64 GUI engine that provided optimal 2D performance with either single-cycle EDO memory or high-speed SGRAM. The 3D Rage II chip was an enhanced, pin compatible version of the 3D Rage accelerator. The second-generation PCI-bus compatible chip boosted 2D performance by 20 percent and added support for MPEG-2 (DVD) playback. The chip also had driver support for Microsoft Direct3D and Reality Lab, QuickDraw 3D Rave, Criterion RenderWare, and Argonaut BRender. OpenGL drivers are available for the professional 3D and CAD community and Heidi drivers are available for AutoCAD users. Drivers are also provided in operating systems including Windows 95, Windows NT, the Mac OS, OS/2, and Linux. ATI also shipped a TV encoder companion chip for RAGE II, the ImpacTV chip.
RAGE II was integrated into several Macintosh Computers, including the Macintosh G3 (Beige), Power Mac 6500. In IBM-compatible PCs, several motherboards and video cards used the chipset as well including: the 3D Xpression+, the 3D Pro Turbo, and the original All-in-Wonder.
The 3D Rage IIc was the last version of the Rage II core, it offered optional AGP support. The Rage IIc was integrated into one Macintosh computer, the original iMac G3/233 (Rev. A.).

Famous quotes containing the word rage:
“Fanaticism is to superstition what delirium is to fever, and what rage is to anger. The man visited by ecstasies and visions, who takes dreams for realities is an enthusiast; the man who supports his madness with murder is a fanatic.”
—Voltaire [François Marie Arouet] (1694–1778)
