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 clocked the core speed at 772 MHz. The GDDR5 RAM is set to run at a frequency of 1002 MHz on this specific model. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.
Compare that to the GeForce GTX 590, which has a clock frequency of 607 MHz and a GDDR5 memory frequency of 855 MHz. It also makes use of a 384-bit bus, and makes use of a 40 nm design. It features 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 590 should in theory be quite a bit superior to the GeForce GTX 580 3GB in general. (explain)
Texel RateThe GeForce GTX 590 will be a lot (approximately 57%) more effective at AF than the GeForce GTX 580 3GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 590 is superior to the GeForce GTX 580 3GB, 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 (measured in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
