Look here, some more speculation on the power of the NV20. The German ZDNet has an article, in German obviously (but you can use Babelfish for a half-assed translation). The guys from The Register have their own interpretation. First of all, there seems to be a programmable pipeline if developers use DirectX8. This allows for optimisation when it comes to geometry, texturing, shading and lighting. As for performance, the NV20 should be up to 7x faster than the GeForce2 Ultra (according to ZDNet), most of the increase coming from an improved memory architecture. It will support 250mhz DDR SDRAM, and the chip's clock core should be higher than 250mhz. As for a release date, card manufacturers will be getting samples in December, so products should become available in January or February.
