In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1800 GTO˛ are very slightly better than the Nvidia GeForce 6800 Ultra.

The Radeon X1800 GTO˛ was released less than a year after the GeForce 6800 Ultra, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon X1800 GTO˛ has 256 MB more video memory than the GeForce 6800 Ultra, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the GeForce 6800 Ultra has superior memory performance.

The GeForce 6800 Ultra has 3.5 GB/sec greater memory bandwidth than the Radeon X1800 GTO˛, which means that the memory performance of the GeForce 6800 Ultra is marginally better than the Radeon X1800 GTO˛.

The Radeon X1800 GTO˛ has 12 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the Radeon X1800 GTO˛ is 4 and the actual shader performance of the GeForce 6800 Ultra is 9. The GeForce 6800 Ultra having 5 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 6800 Ultra delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon X1800 GTO˛.

The Radeon X1800 GTO˛ requires 48 Watts to run and the GeForce 6800 Ultra requires 124 Watts. The GeForce 6800 Ultra requires 76 Watts more than the Radeon X1800 GTO˛ 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 Radeon X1800 GTO˛.
