"I was browsing nVidia's forum over @ Fools, and there was a link to Reactor Critical. Here's what they have to say about NV25.
Long-awaited NV25 based adapters. This graphics processor that have similar capabilities compared with XGPU is a lot more powerful than GeForce3 Ti500. Since it is manufactured using 0.13 microns technology, it has a lot of chances to be clocked at the very high levels. The GPU comes in January/February 2002, while professional boards should be available in the second quarter.
ELSA is going to launch two boards based on NV25GL processor, both supports two LCD monitors, though, we do not know whether there are two integrated TMDS transmitters or only one and the second is external.
NV25 that works on 275 MHz. 128 MB DDR SDRAM @ 250 MHz.
NV25 that works on 300 MHz. 128 MB DDR SDRAM @ 330 MHz.
So, this is what a high-end NV25 part *might* look like...
Rumoured 6 Pixel pipelines
Core freq: 300 MHz.
Memory: 660 MHz. (eff) ~ 10.5 GB/sec BW, assuming they stay with 128-bit data paths.
Supports TwinView
Supports (finally) Hardware iDCT
More powerful T&L unit, to include a second Vertex Shader
Can't find the link, but there's a rumour stating that we can expect Voodoo5 5500-esque Anti-Aliasing feature. The presumption is that the NV25 will bring a Rotated-Grid AA implementation to the table.
.13u Manufacturing process
It really does sound like a pretty amazing chip. I would be willing to bet we'll be hearing a lot more in the way of rumours as the New Year approaches." - nv news
