Compare any two graphics cards:
GeForce GTX 580 vs Geforce GTX 680
IntroThe GeForce GTX 580 uses a 40 nm design. nVidia has set the core speed at 772 MHz. The GDDR5 memory works at a frequency of 1002 MHz on this card. It features 512 SPUs along with 64 Texture Address Units and 48 ROPs.
Compare that to the Geforce GTX 680, which uses a 28 nm design. nVidia has set the core speed at 1006 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this specific model. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 580 should be 0% quicker than the Geforce GTX 680 in general, due to its higher bandwidth. (explain)
Texel RateThe Geforce GTX 680 will be quite a bit (approximately 161%) better at texture filtering than the GeForce GTX 580. (explain)
Pixel RateThe GeForce GTX 580 is a bit (more or less 15%) more effective at FSAA than the Geforce GTX 680, and also able to handle higher resolutions without slowing down too much. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
