Compare any two graphics cards:
GeForce GTX Titan Black vs Radeon HD 3850 512MB
IntroThe GeForce GTX Titan Black has a clock frequency of 889 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit bus, and uses a 28 nm design. It is comprised of 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.Compare those specifications to the Radeon HD 3850 512MB, which comes with a clock frequency of 668 MHz and a GDDR3 memory speed of 828 MHz. It also makes use of a 256-bit memory bus, and makes use of a 55 nm design. It is comprised of 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX Titan Black should theoretically perform a lot faster than the Radeon HD 3850 512MB overall. (explain)
Texel RateThe GeForce GTX Titan Black should be much (more or less 1896%) better at AF than the Radeon HD 3850 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is a better choice, by far. (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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
