Compare any two graphics cards:
Geforce GTX 680 vs Radeon HD 7970
IntroThe Geforce GTX 680 has a clock frequency of 1006 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is made up of 1536 SPUs, 128 TAUs, and 32 ROPs.
Compare all that to the Radeon HD 7970, which features a GPU core clock speed of 925 MHz, and 3072 MB of GDDR5 RAM running at 1375 MHz through a 384-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 7970 should be a lot faster than the Geforce GTX 680 in general. (explain)
Texel RateThe Geforce GTX 680 will be a bit (more or less 9%) faster with regards to texture filtering than the Radeon HD 7970. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Geforce GTX 680 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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core 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 processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
