In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 Ultra are very slightly better than the AMD Radeon HD 2600 Pro.

The HD 2600 was released over a year more recently than the GeForce 6800 Ultra, and so the HD 2600 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 HD 2600 Pro 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 19.2 GB/sec greater memory bandwidth than the HD 2600, which means that the memory performance of the GeForce 6800 Ultra is slightly better than the HD 2600.

The Radeon HD 2600 Pro has 120 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the HD 2600 is 72 and the actual shader performance of the GeForce 6800 Ultra is 9. The HD 2600 having 63 better shader performance is not particularly notable, as altogether the GeForce 6800 Ultra performs better when taking into account other relevant data.

The Radeon HD 2600 Pro requires 35 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 400 Watts for the HD 2600. The GeForce 6800 Ultra requires 89 Watts more than the HD 2600 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 HD 2600.

GPU Mini Review

Mini ReviewRadeon HD 2600 Pro is a middle-class GPU based on the 65nm variant of the second unified shader architecture, R600.
It's based on the RV630 Core and offers 120 Shader Processing Units, 8 TMUs and 4 ROPs a 128-bit memory interface of standard DDR2. The central unit runs at 600MHz and the memory clock runs at up to 500MHz.
Its performance is, overall, below the average and so today's games are only playable at unattractive resolutions and using low (on some) or medium (maybe) presets and DirectX 11 games aren't supported.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
