Compare any two graphics cards:
GeForce GTX 480 vs GeForce GTX 570
IntroThe GeForce GTX 480 has a GPU core speed of 700 MHz, and the 1536 MB of GDDR5 RAM runs at 924 MHz through a 384-bit bus. It also is made up of 480 Stream Processors, 60 Texture Address Units, and 48 ROPs.
Compare those specs to the GeForce GTX 570, which makes use of a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 memory is set to run at a speed of 950 MHz on this specific card. It features 480 SPUs along with 60 Texture Address Units and 40 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 480 should theoretically be a bit better than the GeForce GTX 570 in general. (explain)
Texel RateThe GeForce GTX 570 should be just a bit (more or less 5%) more effective at anisotropic filtering than the GeForce GTX 480. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 480 is the winner, not by a very large margin though. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface 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 higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the bandwidth is, the lower the ability to get to the max fill rate.
