Title: NVIDIA GeForce 7800
Description: Our colleagues of HKEPC have published today the specifications of the future NVIDIA G70 chip to be released next June 22. Launched in GTX, GT and standard version, this chip sales name would be GeForce 7800.

This chip will utilize the 110 nm fabrication process of TSMC and will feature in GTX version 24 pixel pipelines and 8 vertex engines. It is respectively 50 and 33% higher than the GeForce 6800 Ultra. No details on the pipes characteristics have been communicated, but we can imagine that they will be quite close to the GeForce 6.

The GPU would be clocked at 430 MHz, instead of 425 to 400 MHZ for a 6800 Ultra and the GDDR3 memory would run at a frequency of 600MHz (1200 Mbits/s per pin) instead of 550 MHz for current graphic cards. The GeForce 7800 will be SLI compatible in GTX version. In terms of functionalities, a CineFX 4.0 has been mentioned even if we don’t know whether this upgrade from 3 to 4 is nothing else than marketing .


NVIDIA recommends a 400 Watts power supply able to support 26 A on the 12V line for a 7800 GTX, and 500 Watts 34A on the 12V for the two other graphic cards. To give you an idea, NVIDA recommends using a 500 to 550 Watt power supply able to provide 30A on the 12V line for a configuration based on two GeForce 6800 Ultra.
