The NV30 (GeWhiz 5) will use 525Mhz (1050Mhz DDR) memory, have 7 rendering pipelines, one oil pipeline and quad monkey brains. In addition to the AGP slot it will require external 240v, three phase AC power. It will run dual monitors and one etch-e-sketch (with anti-aliasing) simultaneously.
Core speed has not been finalized yet, but rumor is that it will run Quake III Arena at playable framerates.
