Compare any two graphics cards:
GeForce GTX 580 vs Geforce GTX 680
IntroThe GeForce GTX 580 makes use of a 40 nm design. nVidia has set the core speed at 772 MHz. The GDDR5 memory runs at a frequency of 1002 MHz on this model. It features 512 SPUs as well as 64 Texture Address Units and 48 Rasterization Operator Units.
Compare that to the Geforce GTX 680, which features clock speeds of 1006 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 580 should perform a little bit faster than the Geforce GTX 680 in general. (explain)
Texel RateThe Geforce GTX 680 should be much (about 161%) better at AF than the GeForce GTX 580. (explain)
Pixel RateThe GeForce GTX 580 will be just a bit (about 15%) faster with regards to anti-aliasing than the Geforce GTX 680, and also will be able to handle higher screen 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.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
