Compare any two graphics cards:
GeForce 8800 Ultra vs Radeon HD 3850 X2
IntroThe GeForce 8800 Ultra makes use of a 90 nm design. nVidia has clocked the core frequency at 612 MHz. The GDDR3 RAM is set to run at a frequency of 1080 MHz on this card. It features 128 SPUs along with 64 TAUs and 24 ROPs.Compare those specifications to the Radeon HD 3850 X2, which uses a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 memory is set to run at a frequency of 828 MHz on this specific model. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 3850 X2 will be 2% faster than the GeForce 8800 Ultra in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce 8800 Ultra should be much (approximately 83%) faster with regards to texture filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe Radeon HD 3850 X2 should be a lot (approximately 46%) better at anti-aliasing than the GeForce 8800 Ultra, and will be able to handle higher screen resolutions better. (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 information (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once 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 higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
