Compare any two graphics cards:
GeForce GTX 470 vs Radeon HD 6970
IntroThe GeForce GTX 470 comes with a core clock frequency of 607 MHz and a GDDR5 memory speed of 837 MHz. It also uses a 320-bit memory bus, and makes use of a 40 nm design. It is made up of 448 SPUs, 56 TAUs, and 40 Raster Operation Units.
Compare those specifications to the Radeon HD 6970, which uses a 40 nm design. AMD has set the core frequency at 880 MHz. The GDDR5 memory is set to run at a frequency of 1375 MHz on this specific model. It features 1536 SPUs along with 96 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 6970 should in theory perform quite a bit faster than the GeForce GTX 470 in general. (explain)
Texel RateThe Radeon HD 6970 is quite a bit (approximately 149%) more effective at texture filtering than the GeForce GTX 470. (explain)
Pixel RateThe Radeon HD 6970 will be a bit (about 16%) more effective at anti-aliasing than the GeForce GTX 470, and also will be capable of handling higher resolutions without losing too much performance. (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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
