In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 Ultra are noticeably better than the AMD Radeon X1650 PowerColor 256MB Edition.

The X1650 PowerColor was released over a year more recently than the GeForce 6800 Ultra, and so the X1650 PowerColor 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 Radeon X1650 PowerColor 256MB Edition 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 6800 Ultra has 28.8 GB/sec greater memory bandwidth than the X1650 PowerColor, which means that the memory performance of the GeForce 6800 Ultra is slightly better than the X1650 PowerColor.

The Radeon X1650 PowerColor 256MB Edition has 12 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the X1650 PowerColor 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 noticeably smoother and more efficient experience when processing graphical data than the X1650 PowerColor.

The GeForce 6800 Ultra requires 124 Watts to run but there is no entry for the X1650 PowerColor. We would recommend a PSU with at least 350 Watts for the X1650 PowerColor.
