Compare any two graphics cards:
GeForce 8800 Ultra vs GeForce 9800 GX2
IntroThe GeForce 8800 Ultra features a clock speed of 612 MHz and a GDDR3 memory frequency of 1080 MHz. It also makes use of a 384-bit bus, and uses a 90 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 24 ROPs.Compare all that to the GeForce 9800 GX2, which features a clock speed of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also features a 256-bit bus, and uses a 65 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9800 GX2 should be quite a bit faster than the GeForce 8800 Ultra overall. (explain)
Texel RateThe GeForce 9800 GX2 will be a lot (approximately 96%) better at anisotropic filtering than the GeForce 8800 Ultra. (explain)
Pixel RateThe GeForce 9800 GX2 will be quite a bit (approximately 31%) better at anti-aliasing than the GeForce 8800 Ultra, and should be able to handle higher screen resolutions without losing too much performance. (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 (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
