Compare any two graphics cards:
GeForce GTX Titan Black vs Radeon HD 3870 X2 512MB
IntroThe GeForce GTX Titan Black features a GPU core clock speed of 889 MHz, and the 6144 MB of GDDR5 memory is set to run at 1750 MHz through a 384-bit bus. It also features 2880 Stream Processors, 240 TAUs, and 48 ROPs.Compare all that to the Radeon HD 3870 X2 512MB, which uses a 55 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific card. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTX Titan Black should in theory be a lot faster than the Radeon HD 3870 X2 512MB overall. (explain)
Texel RateThe GeForce GTX Titan Black will be quite a bit (about 708%) better at AF than the Radeon HD 3870 X2 512MB. (explain)
Pixel RateThe GeForce GTX Titan Black is much (more or less 62%) more effective at FSAA than the Radeon HD 3870 X2 512MB, and also able to handle higher screen resolutions while still performing well. (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 (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type 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, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
