Looking around (again) I found this:
Nvidia has just announced its G70, Geforce 7800GTX card still based on 110 nm design while ATI is taking a risk by moving to a 90 nanometre process. ATI is about to get into production with its 90nm R520, following by the RV530 and RV515, both also 90 nanometre based. It got things right but it was not that easy, it took ATI three tape outs to get there.
Once ATI reveals the R520, Nvidia won't have any other choice than to release a faster clocked version of G70, Geforce 7800 possibly known as Ultra. We learned that this chip will still be based on 110 nanometres as Nvidia is not ready to jump to the 90 naometre yet.
Basically, we are talking about same chip but different clock, but let me remind you that we haven’t got a huge performance increase running this chip at 500/1400 MHz with a 4000+ CPU. In order to get the real performance, you need to have a faster CPU and F55 or FX57 would be good for the task. At these speeds, you need to use ultra high settings with FSAA and Aniso on to maximum at resolutions such as 1600x1200 in order to show the difference. After G70 Ultra and R520 comes R580 and Nvidia 90 nanometre part but I doubt that there will be enough time to release those chips in 2005. It's rather likely that you will see these chips in early 2006 only.
Seems 90nm for Nvidia at least will be 2006 - ultras will just be clocked versions of GTX's - Meaning perhaps a 7900 series in Q1 06 - the '9' will be a good marketing choice as it shows 90nm.
This could be the opening ATI was banking on - perhaps the R520 will hold the fastest crown until that time, although judge me on what I say when I say anything below 1600*1200 and an FX55/57 fully overclocked - it will be difficult to see the performance increases.
Only when dual core and physics come online will we be able to unleash the full power of these technological terrors.
