The G71 is believed to be a optimized dual-slot edition of the regular GeForce 7800 GTX. After NVIDIA learned that ATI will use a dual-slot design for its R520 it gave its engineers green light to trash every speed record set by the G70 and ATI's upcoming R520 by making a new dual-slot GeForce 7800.
The G71 will be made on the 110nm process and will be clocked much higher than the GeForce 7800 GTX which is clocked at 430MHz. Some sources even claim that NVIDIA was able to clock several boards at 800MHz without using exotic cooling! This will force ATI to quickly respond with its 32 pixel pipeline R580.
Some features of the G71 (GeForce 7800 Ultra?):
- 110nm process, modestly revised GPUSource: The Inquirer
- unexpected clockspeed
- 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
