Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 580
IntroThe GeForce GTX 570 comes with a GPU core speed of 732 MHz, and the 1280 MB of GDDR5 RAM runs at 950 MHz through a 320-bit bus. It also features 480 Stream Processors, 60 TAUs, and 40 Raster Operation Units.
Compare that to the GeForce GTX 580, which uses a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 RAM runs at a frequency of 1002 MHz on this specific card. It features 512 SPUs as well as 64 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 580 should theoretically be quite a bit better than the GeForce GTX 570 in general. (explain)
Texel RateThe GeForce GTX 580 should be just a bit (approximately 12%) more effective at AF than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 580 will be much (about 27%) more effective at anti-aliasing than the GeForce GTX 570, and will be capable of handling higher resolutions while still performing well. (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 maximum amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus 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 higher the bandwidth is, the faster 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 processed in one second. This number is calculated by multiplying the total number of 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 processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
