Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX 580
IntroThe GeForce 9800 GX2 features a GPU core clock speed of 600 MHz, and the 512 MB of GDDR3 RAM runs at 1000 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 TAUs, and 16 ROPs.Compare those specs to the GeForce GTX 580, which uses a 40 nm design. nVidia has clocked the core frequency at 772 MHz. The GDDR5 RAM runs at a frequency of 1002 MHz on this card. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 580 should perform much faster than the GeForce 9800 GX2 in general. (explain)
Texel RateThe GeForce 9800 GX2 should be a lot (approximately 55%) better at texture filtering than the GeForce GTX 580. (explain)
Pixel RateThe GeForce GTX 580 is a lot (more or less 93%) better at FSAA than the GeForce 9800 GX2, and will be able to handle 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: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core 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 processed in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
