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 features a 384-bit bus, and uses a 90 nm design. It is made up of 128 SPUs, 64 TAUs, and 24 Raster Operation Units.Compare those specs to the GeForce 9800 GX2, which uses a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory works at a speed of 1000 MHz on this particular card. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9800 GX2 should theoretically perform much faster than the GeForce 8800 Ultra in general. (explain)
Texel RateThe GeForce 9800 GX2 will be quite a bit (about 96%) more effective at anisotropic filtering than the GeForce 8800 Ultra. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 9800 GX2 is superior to the GeForce 8800 Ultra, and very much so. (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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be processed per second. This figure 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record 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 clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
