Compare any two graphics cards:
GeForce GTX Titan Black vs Radeon HD 3870 X2 512MB
IntroThe GeForce GTX Titan Black has clock speeds of 889 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 memory. It features 2880 SPUs along with 240 Texture Address Units and 48 ROPs.Compare those specs to the Radeon HD 3870 X2 512MB, which comes with a clock speed of 825 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit bus, and uses a 55 nm design. It features 320(64x5) SPUs, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the GeForce GTX Titan Black should theoretically be much superior to the Radeon HD 3870 X2 512MB in general. (explain)
Texel RateThe GeForce GTX Titan Black should be a lot (more or less 708%) faster with regards to texture filtering than the Radeon HD 3870 X2 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is a better choice, and very much so. (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 largest amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 reach the maximum fill rate.
