Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX 260 Core 216
IntroThe GeForce 9800 GX2 features a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 RAM is set to run at 1000 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 ROPs.Compare all that to the GeForce GTX 260 Core 216, which comes with a GPU core clock speed of 576 MHz, and 896 MB of GDDR3 memory running at 999 MHz through a 448-bit bus. It also is made up of 216 Stream Processors, 72 TAUs, and 28 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9800 GX2 will be 14% faster than the GeForce GTX 260 Core 216 overall, because of its greater data rate. (explain)
Texel RateThe GeForce 9800 GX2 will be quite a bit (more or less 85%) better at texture filtering than the GeForce GTX 260 Core 216. (explain)
Pixel RateThe GeForce 9800 GX2 is a bit (about 19%) better at AA than the GeForce GTX 260 Core 216, and also should be able to handle higher screen 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 max amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
