Compare any two graphics cards:
GeForce GTX 295 vs GeForce GTX 580 3GB
IntroThe GeForce GTX 295 features core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 240 SPUs along with 80 TAUs and 28 ROPs.Compare that to the GeForce GTX 580 3GB, which uses a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 memory is set to run at a frequency of 1002 MHz on this model. It features 512 SPUs as well as 64 TAUs and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 295 should be a small bit faster than the GeForce GTX 580 3GB overall. (explain)
Texel RateThe GeForce GTX 295 is a lot (about 87%) more effective at texture filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 580 3GB is superior to the GeForce GTX 295, though only just barely. (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 Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
