Mac / ADC / VGA / AGP
Graphics Acceleration for the Power Mac G4
Powerful 3D Graphics Performance
Powered by the Radeon™ 7500 GPU and 32MB DDR memory for advanced 3D graphics, the Radeon™ 7500 delivers immersive, realistic 32-bit color graphics in both Mac® OS X and Mac® OS 9 with exceptional performance. Featuring rapid acceleration of graphics-intense OpenGL®, QuickDraw® 3D and RAVE® applications, the Radeon™ 7500 supports high-resolution 3D gaming up to 2048x1536.

The CHARISMA ENGINE™ supports full Transformation, Clipping and Lighting (T&L) at 40 million triangles/second peak processing capability, while PIXEL TAPESTRY™, the RADEON™ 7500 rendering engine, powers an incredible 1.6 gigatexels/second for fast fill rates in 32-bit at high resolutions.

Rating: 5/5 How awesome that OWC has this product! April 4, 2017 So I had a goal to bring and old G4 (2000 model) powermac up to speed as a legacy system that could run all my old software (read my review of the 120GB OWC Mercury Pro Legacy 3.5-inch IDE/ATA Solid-State Drive Kit).

The G4 I got off of ebay had the ATI rage 128 pro, which could not power my 2005 era 20" Apple LED cinema display. The 128 pro has 16 megs of video ram, this 7500 that OWC sells has 32 megs of video ram. That right there made the difference and now the Apple cinema display works great.

Bottom line, if you're trying to upgrade, or bring and old powermac back to life, OWC is the place go! And their support is excellent too.
