Just a fair warning...The link may die anytime soon, as it's a cached link.

Guys, VRzone posted this, but NVidia made them pull it down... Thus here's the googled cached page...Gotta love google...

NVIDIA is likely to make a switch when the process technology is more mature like towards end of the year. No doubt, the core frequency can be clocked higher on finer process. However, we can't rule out the possibility of releasing 7800Ultra on the 90nm G71 core when R520 launched since volume production are not expected for such a high-end GPU. Of course it could be based on 110nm process initially as INQ has suggested. 32-pipes or not, it is still unknown.
Looks like we might see close to 800mhz clocks after all....
