Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce 9800 GX2
IntroThe GeForce 9500 GT 512MB GDDR3 uses a 55 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 memory works at a speed of 800 MHz on this particular model. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare those specifications to the GeForce 9800 GX2, which has a core clock frequency of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also uses a 256-bit memory bus, and uses a 65 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 9800 GX2 should in theory be much better than the GeForce 9500 GT 512MB GDDR3 overall. (explain)
Texel RateThe GeForce 9800 GX2 is much (more or less 773%) better at AF than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 9800 GX2 is a better choice, by a large margin. (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 data (measured in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
