Compare any two graphics cards:
GeForce GTX 570 vs Geforce GTX 760
IntroThe GeForce GTX 570 features a clock speed of 732 MHz and a GDDR5 memory speed of 950 MHz. It also uses a 320-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 60 TAUs, and 40 Raster Operation Units.
Compare those specifications to the Geforce GTX 760, which features a core clock frequency of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It features 1152 SPUs, 96 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 760 is 26% quicker than the GeForce GTX 570 in general, due to its higher data rate. (explain)
Texel RateThe Geforce GTX 760 should be quite a bit (about 114%) faster with regards to texture filtering than the GeForce GTX 570. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Geforce GTX 760 is superior to the GeForce GTX 570, but only just. (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 over 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 type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
