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 frequency at 772 MHz. The GDDR5 memory runs at a frequency of 1002 MHz on this particular card. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.
Compare those specs to the Geforce GTX 680, which features a core clock speed of 1006 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 580 should in theory be a little bit faster than the Geforce GTX 680 in general. (explain)
Texel RateThe Geforce GTX 680 is a lot (more or less 161%) better at AF than the GeForce GTX 580. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 580 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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
