Compare any two graphics cards:
GeForce GTX 295 vs GeForce GTX 580 3GB
IntroThe GeForce GTX 295 uses a 55 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory runs at a frequency of 999 MHz on this particular model. It features 240 SPUs as well as 80 Texture Address Units and 28 ROPs.Compare those specs to the GeForce GTX 580 3GB, which makes use of a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 RAM runs at a speed of 1002 MHz on this model. It features 512 SPUs along with 64 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 295 should in theory be just a bit superior to the GeForce GTX 580 3GB overall. (explain)
Texel RateThe GeForce GTX 295 is quite a bit (more or less 87%) more effective at AF than the GeForce GTX 580 3GB. (explain)
Pixel RateThe GeForce GTX 580 3GB is just a bit (more or less 15%) better at anti-aliasing than the GeForce GTX 295, and will be capable of handling higher screen resolutions better. (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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
