Compare any two graphics cards:
GeForce 8500 GT vs GeForce 9800 GX2
IntroThe GeForce 8500 GT features a core clock frequency of 450 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit bus, and uses a 80 nm design. It features 16 SPUs, 8 TAUs, and 4 ROPs.Compare those specifications to the GeForce 9800 GX2, which makes use of a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9800 GX2 will be 900% faster than the GeForce 8500 GT in general, because of its higher data rate. (explain)
Texel RateThe GeForce 9800 GX2 will be a lot (about 2033%) better at AF than the GeForce 8500 GT. (explain)
Pixel RateThe GeForce 9800 GX2 will be a lot (more or less 967%) faster with regards to full screen anti-aliasing than the GeForce 8500 GT, and also capable of handling higher screen resolutions more effectively. (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 information (in units of megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
