We still don't know whether the NVIDIA G71 will be the GeForce 7800 GT, a mid-range card or the ATI R520 killer.
VR-Zone recently posted an article about the G71 but they deleted it for unknown reasons. However, Google was quick enough to snap a cache version of the page.
The article stated the G71 will be NVIDIA's secret weapon against ATI's R520. Contrary to other reports the G71 may be made on the 90nm process, instead of 110nm like the GeForce 7800 GTX:
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.
