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

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 670 should in theory be a lot faster than the GeForce GTX 570 in general. (explain)
Texel RateThe Geforce GTX 670 will be a lot (approximately 133%) faster with regards to anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateBoth cards have exactly the same pixel fill rate, so theoretically they should be equally good at at full screen anti-aliasing, 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 data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount 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 calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
