In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7900 GS are noticeably better than the Nvidia GeForce 6800 Ultra.

The GeForce 7900 GS was released over a year more recently than the GeForce 6800 Ultra, and so the GeForce 7900 GS is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6800 Ultra.

The GeForce 7900 GS and the GeForce 6800 Ultra have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 7900 GS has 7 GB/sec greater memory bandwidth than the GeForce 6800 Ultra, which means that the memory performance of the GeForce 7900 GS is marginally better than the GeForce 6800 Ultra.

The GeForce 7900 GS has 20 Shader Processing Units and the GeForce 6800 Ultra has 22. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, we sadly do not have enough data in this area to complete the comparison.

The GeForce 7900 GS requires 49 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 350 Watts for the GeForce 7900 GS. The GeForce 6800 Ultra requires 75 Watts more than the GeForce 7900 GS to run. The difference is significant enough that the GeForce 6800 Ultra may have an adverse affect on your yearly electricity bills in comparison to the GeForce 7900 GS.
