Compare any two graphics cards:
GeForce GTX 580 3GB vs GeForce GTX 590
IntroThe GeForce GTX 580 3GB uses a 40 nm design. nVidia has set the core frequency at 772 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this card. It features 512 SPUs as well as 64 TAUs and 48 ROPs.
Compare those specs to the GeForce GTX 590, which has a GPU core clock speed of 607 MHz, and 1536 MB of GDDR5 memory set to run at 855 MHz through a 384-bit bus. It also is made up of 512 Stream Processors, 64 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 590 should in theory perform much faster than the GeForce GTX 580 3GB overall. (explain)
Texel RateThe GeForce GTX 590 is much (approximately 57%) better at texture filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 590 is a better choice, by a large margin. (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.
One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.
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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 applied in one second. This number is calculated by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
