Compare any two graphics cards:
GeForce GTX 570 vs Geforce GTX 670
IntroThe GeForce GTX 570 features a clock speed of 732 MHz and a GDDR5 memory speed of 950 MHz. It also makes use of a 320-bit memory bus, and uses a 40 nm design. It is made up of 480 SPUs, 60 TAUs, and 40 ROPs.
Compare all that to the Geforce GTX 670, which features a core clock frequency of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Geforce GTX 670 should theoretically be a lot superior to the GeForce GTX 570 in general. (explain)
Texel RateThe Geforce GTX 670 should be quite a bit (about 133%) more effective at anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateBoth cards have exactly the same pixel fill rate, so in theory they should perform equally good at at FSAA, and be able to handle the same resolutions. (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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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.
