Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce 9800 GX2
IntroThe GeForce 8600 GT 256MB GDDR3 has a core clock frequency of 540 MHz and a GDDR3 memory speed of 700 MHz. It also makes use of a 128-bit memory bus, and makes use of a 80 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specifications to the GeForce 9800 GX2, which comes with a core clock frequency of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also features a 256-bit memory bus, and makes use of a 65 nm design. It features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 9800 GX2 should in theory be quite a bit superior to the GeForce 8600 GT 256MB GDDR3 in general. (explain)
Texel RateThe GeForce 9800 GX2 will be quite a bit (approximately 789%) more effective at AF than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 9800 GX2 is the winner, 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 largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the video card can 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
