Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 7970
IntroThe Geforce GTX 670 makes use of a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this card. It features 1344 SPUs as well as 112 TAUs and 32 ROPs.
Compare all that to the Radeon HD 7970, which uses a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory works at a speed of 1375 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 7970 should theoretically perform much faster than the Geforce GTX 670 in general. (explain)
Texel RateThe Radeon HD 7970 will be a bit (approximately 16%) better at texture filtering than the Geforce GTX 670. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 7970 is the winner, but 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.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range 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 worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling 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 its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
