Some inside information from theinquirer.net-

The "Faster G70", which is how the G71 is being called internally now, targets almost insane clock speeds. We have learned that several boards achieved a clock speed of 800MHz, which just goes to prove that tweaks being done in 110nm G71 core will make R520 tremble, and force ATI to respond with its 32-pipe R580 as soon as possible. However, we have to warn you that we haven't been able to find out in what environment this clockspeed was achieved. But it was achieved using new and improved two-slot cooling, not water or phase-change cooling...
So, to sum what we know about G71, possibly dubbed the 7800 Ultra:
- 110nm process, modestly revised GPU
- unexpected clockspeed (up till' this story, of course)
- dual-slot aluminium cooling with at least four heatpipes
- ultra-silent, large-fin large-diameter fan
- 512 MB of GDDR-3 memory, provided by Samsung. Capacity of the chips: unknown
