GeForce GTX 285 1GB 204 Watts
Radeon HD 6970 250 Watts
Difference: 46 Watts (23%)

Memory Bandwidth

As far as performance goes, the Radeon HD 6970 should in theory be a small bit superior to the GeForce GTX 285 1GB in general. (explain)

Radeon HD 6970 176000 MB/sec
GeForce GTX 285 1GB 158976 MB/sec
Difference: 17024 (11%)

Texel Rate

The Radeon HD 6970 should be much (more or less 63%) more effective at anisotropic filtering than the GeForce GTX 285 1GB. (explain)

Radeon HD 6970 84480 Mtexels/sec
GeForce GTX 285 1GB 51840 Mtexels/sec
Difference: 32640 (63%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6970 is the winner, by far. (explain)

Radeon HD 6970 28160 Mpixels/sec
GeForce GTX 285 1GB 20736 Mpixels/sec
Difference: 7424 (36%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
