90nm GeForce 7800?

Thats what it says, obviously using the same kind of process in hopes of keeping power consumption down, but what was interesting, was the article stated that Nvidia developed the 7800GTX for mobile first then branched off and developed it for the desktop.

What's more interesting is, if that thing is really 90nm...it could hit clock speeds of 600Mhz...since they clocked it to just 400...I'm guessing it's a typo...but if not, a 90nm G70 could really kick some ass...I didn't expect to see them doing volume production on high end 90nm chips for at least a few more months...
 
We would hope, but I am guessing heat dissapation would be a big issue, when you start ramping up the clockspeed, depending on what type of laptop you have, and the cooling available.

But as with the case of the 6800 Go you could sacrifice its power saving features, and easilly obtain 6800 Go Ultra speeds and beyond, many I9300 owners can prove that.

I seem to recall the go 6800 ultra was clocked higher than the regular ultra...so it seems odd that they would clock this one lower especially if it was in fact 90nm...
 
True, but I think it only had 8 pipes, thus allowing higher clockrates with equal (or less) heat generation.

it has 12 pipes, I have one :)

I looked around and I think they were just mistaken about the 90nm thing, that just doesn't make sense.

It may not make sense, but it's true. According to nVidia's Technical Briefs: PowerMizer 6.0 nVidia says:

nVidia said:
Advanced manufacturing fabrication and packaging processes, tuned specifically for mobile needs, provide the industry’s lowest power operation capability (down to the latest 0.09 micron process technology, running at low voltage, and power-dissipative bare-die flip-chip packaging).

nVidia said:
An increase in voltage results in an exponential increase in consumed power. Therefore, managing voltage is extremely important for managing power consumption. GeForce Go 7 Series GPUs use an advanced semiconductor process technology to operate at the lowest voltage of any mobile GPU. Other GPUs use a higher voltage at all times, or scale voltage up to deliver performance, thus shortening battery life. The finer process geometries in the NVIDIA solutions—down to a power-saving 0.09 micron low-voltage process—enable a design that can run at lower nominal voltages.

So nVidia has managed to get 0.09micron parts out before ATI - interesting - I wonder if they will have problems with a desktop transition.
 
The Go 7800GTX is 110nm. But there are 90nm parts in the Go 7800 Series.
