Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 680
IntroThe Geforce GTX 670 has a core clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.
Compare those specs to the Geforce GTX 680, which features GPU core speed of 1006 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also features 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 680 is 0% faster than the Geforce GTX 670 overall, because of its higher data rate. (explain)
Texel RateThe Geforce GTX 680 is quite a bit (more or less 26%) faster with regards to anisotropic filtering than the Geforce GTX 670. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Geforce GTX 680 is the winner, though only just barely. (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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
