Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6970
IntroThe GeForce GTX 470 uses a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 memory works at a speed of 837 MHz on this particular card. It features 448 SPUs along with 56 TAUs and 40 Rasterization Operator Units.
Compare all that to the Radeon HD 6970, which uses a 40 nm design. AMD has clocked the core frequency at 880 MHz. The GDDR5 memory works at a frequency of 1375 MHz on this specific card. It features 1536 SPUs along with 96 Texture Address Units and 32 ROPs.

Radeon HD 6970 wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the Radeon HD 6970 wins overall, by 41 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 6970 should in theory be much superior to the GeForce GTX 470 overall. (explain)
Texel RateThe Radeon HD 6970 should be quite a bit (more or less 149%) better at AF than the GeForce GTX 470. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 6970 is superior to the GeForce GTX 470, though only just barely. (explain)
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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
