In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3800 series are significantly better than the Nvidia GeForce 7900 GTO.

The HD 3800 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The HD 3800 was released over a year more recently than the GeForce 7900 GTO, and so the HD 3800 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 7900 GTO.

The GeForce 7900 GTO and the Radeon HD 3800 series 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 GTO has 42.2 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the GeForce 7900 GTO is noticeably better than the HD 3800.

The GeForce 7900 GTO has 24 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the GeForce 7900 GTO is 16 and the actual shader performance of the HD 3800 is 0. The GeForce 7900 GTO having 16 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 7900 GTO delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The GeForce 7900 GTO requires 81 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 400 Watts for the GeForce 7900 GTO.
