The Chip
The 8800GT is built off the code name G92 architecture, which is a derivative of the G80 architecture that provides the foundation for the 8800GTS/GTX systems. The main changes made to the G92 are the 65nm production process, and rolling in the display, and video processing chips directly into the GPU. The number of transistors has increased from 681 million to 754 million. Despite the larger number of transistors, the G92 chip is almost half the size of the G80 and consumes significantly less power, due to the 65nm technology.
Differences with GTS and GTX
The 8800GT features less texture and stream processing capabilities than its more expensive brethren. The GT also has a narrower memory bus between the GPU and the video RAM, however actual memory bandwidth is only 10% less than that found on the GTS due to the higher clockspeed found on the GT. In real world applications the smaller bandwidth becomes an issue when running at resolutions near 1080p and above, with anti-aliasing active.
