Compare any two graphics cards:
GeForce 8800 GTX vs Radeon HD 3850 X2
IntroThe GeForce 8800 GTX makes use of a 90 nm design. nVidia has clocked the core speed at 575 MHz. The GDDR3 memory runs at a speed of 900 MHz on this particular model. It features 128 SPUs as well as 64 Texture Address Units and 24 ROPs.Compare those specifications to the Radeon HD 3850 X2, which features core clock speeds of 668 MHz on the GPU, and 828 MHz on the 512 MB of GDDR3 memory. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3850 X2, in theory, should perform a lot faster than the GeForce 8800 GTX in general. (explain)
Texel RateThe GeForce 8800 GTX is a lot (about 72%) better at texture filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe Radeon HD 3850 X2 will be a lot (about 55%) more effective at FSAA than the GeForce 8800 GTX, and able to handle higher 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should 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 higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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. Pixel rate 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 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
