Thread: Investigating the GeForce 7900GTX

Based on the G71 core, the GeForce 7900GTX is the most powerful offering from Nvidia aimed at the Radeon X1900XT from AT!.

Yes, the 7900GTX is not different in terms of the Pixel and Vertex shader units when compared to the 7800GTX. The transistor count has also gone down from 304 million transistors in the 7800GTX to 278 million in the 7900GTX. By shrinking the die size and reducing the transistor count, Nvidia claims to have drastically reduced the power consumption of the card, thus cutting down on the heat as well.



As a result, Nvidia was able to bump the clock speeds much higher while consuming less power. The 7900GTX comes with 512 MB ofGDDR3 256-bit memory, similar to its rival the Radeon X1900XT. By default, the G71 is clocked at 650 MHz and the 512 MB memory has a reference clock speed of 1600 MHz.
