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

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 GS, 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 GS.

The HD 3800 has 256 MB more video memory than the GeForce 7900 GS, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the GeForce 7900 GS has superior memory performance.

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

The GeForce 7900 GS has 20 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the GeForce 7900 GS is 9 and the actual shader performance of the HD 3800 is 0. The GeForce 7900 GS having 9 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 7900 GS delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The GeForce 7900 GS requires 49 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 350 Watts for the GeForce 7900 GS.
