First up is the high end G92, a replacement for the 8800 lines. This is coming out in short order, we have heard two dates for it, November 12th and November 5th, the former being the more likely candidate. We have heard internal names of G92_200 and G92_300 for low and high end enthusiast parts respectively.
There is also a value part, the G98, launching in November as well. Seeing as how Nvidia works PR, it will probably not be on the 12th, twice the headlines is just that. The mid-range G96 is taping out really soon, and production is scheduled for next spring, April if all goes well.
The weird thing is that the above codes are for ASICs, that is fab talk. What you guys will see is a new naming convention. For the high-end, 'enthusiast' parts, it will be called D8E, mainstream will be D8P and value will have D8M. These correspond to G92, G96 and G98 respectively.
Notebooks will also have a new naming scheme, and they go one number up. They will be NB9E, NB9P and NB9M, the last letter signifies the same market segment as the desktop parts. Unless they can keep power under control, unlike the last few revs, their fate in this segment looks increasingly grim.
