In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7800 GS are very slightly better than the Nvidia GeForce 6800 XT.

The GeForce 7800 GS was released over a year more recently than the GeForce 6800 XT, and so the GeForce 7800 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 XT.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce 6800 XT and the GeForce 7800 GS have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 7800 GS has 27.2 GB/sec greater memory bandwidth than the GeForce 6800 XT, which means that the memory performance of the GeForce 7800 GS is slightly better than the GeForce 6800 XT.

The GeForce 6800 XT has 12 Shader Processing Units and the GeForce 7800 GS has 16. However, the actual shader performance of the GeForce 6800 XT is 4 and the actual shader performance of the GeForce 7800 GS is 6. The GeForce 7800 GS having 2 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 7800 GS delivers a slightly smoother and more efficient experience when processing graphical data than the GeForce 6800 XT.

The GeForce 7800 GS requires 49 Watts to run but there is no entry for the GeForce 6800 XT. We would recommend a PSU with at least 400 Watts for the GeForce 7800 GS, but we do not have a recommended PSU wattage for the GeForce 6800 XT.
