Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6970
IntroThe GeForce GTX 470 makes use of a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory works at a frequency of 837 MHz on this particular card. It features 448 SPUs along with 56 Texture Address Units and 40 Rasterization Operator Units.
Compare those specs to the Radeon HD 6970, which comes with GPU core speed of 880 MHz, and 2048 MB of GDDR5 RAM running at 1375 MHz through a 256-bit bus. It also features 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 6970, in theory, should be a lot faster than the GeForce GTX 470 overall. (explain)
Texel RateThe Radeon HD 6970 will be a lot (about 149%) more effective at anisotropic filtering than the GeForce GTX 470. (explain)
Pixel RateThe Radeon HD 6970 should be a bit (more or less 16%) better at anti-aliasing than the GeForce GTX 470, and will be able to handle higher resolutions while still performing well. (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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
