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

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 6970 should theoretically be a lot superior to the GeForce GTX 470 in general. (explain)
Texel RateThe Radeon HD 6970 should be much (more or less 149%) faster with regards to texture filtering 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 not by far. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
