Compare any two graphics cards:
GeForce GTX 285 2GB vs GeForce GTX 590
IntroThe GeForce GTX 285 2GB features a clock speed of 648 MHz and a GDDR3 memory speed of 1242 MHz. It also uses a 512-bit memory bus, and makes use of a 55 nm design. It features 240 SPUs, 80 Texture Address Units, and 32 ROPs.Compare all of that to the GeForce GTX 590, which uses a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 memory runs at a speed of 855 MHz on this card. It features 512 SPUs as well as 64 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 590 is 107% faster than the GeForce GTX 285 2GB in general, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 590 will be a lot (more or less 50%) better at texture filtering than the GeForce GTX 285 2GB. (explain)
Pixel RateThe GeForce GTX 590 should be quite a bit (approximately 181%) better at anti-aliasing than the GeForce GTX 285 2GB, and also will be able to handle higher resolutions without slowing down too much. (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 information (measured in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total 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 processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
