Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce 9800 GX2
IntroThe GeForce 9500 GT 512MB GDDR3 comes with a clock frequency of 550 MHz and a GDDR3 memory speed of 800 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce 9800 GX2, which comes with core clock speeds of 600 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9800 GX2 should be much faster than the GeForce 9500 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce 9800 GX2 should be much (about 773%) more effective at anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 9800 GX2 is superior to the GeForce 9500 GT 512MB GDDR3, 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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported across 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 memory, it must be multiplied by 2 again. If 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 per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
