GeForce 7900 GT
Of course, the transition to a thin technical process contributed to an increase in operating frequencies. The nominal frequency of the video chip in 7900GTX was set at 650 MHz. As they say, there was a noticeable difference compared to the standard 430 MHz for 7800GTX. The increase in productivity was in the region of 51%.
In contrast to the 7800GT/GTX pair, this time NVIDIA did not cut functionality by reducing the number of pipelines. Either the new 90 nm technical process turned out to be so good that there was almost no marriage, or the cost of new chips was so low that you can not do "optimization of illiquid assets". Be that as it may, the video processor on the 7900GT is exactly the same as on the 7900GTX.
The nominal frequency of the chip on the 7900GT video card was 450 MHz, which did not differ much from 400 MHz for the 7800GT.

There is no doubt that Nvidia's graphics card, aimed at the price segment 9, turned out to be very successful. The GeForce 7900 GT video adapter inherited all the positive features of the GeForce 7800 GTX, while at the same time becoming much simpler, cheaper and more economical thanks to the use of the new G71 graphics processor.
In real conditions, the new product proved to be excellent, outperforming the Radeon x1800 XL in the vast majority of tests, and in some cases even competing on equal terms with the much more powerful Radeon x1800 XT. To a large extent, this was facilitated by the presence of 24 TMUs, and, as a result, a higher scene fill rate - a parameter that is in demand in games with a large number of texture fetches. Combined with a power consumption level of about 48 watts, which was noticeably lower than those of the GeForce 7800 GT and Radeon X1800 XL, and excellent overclocking potential, this gave every reason to call the Nvidia GeForce 7900 GT the best card in its price range.
