Compare any two graphics cards:
GeForce GTX Titan Black vs Radeon HD 4890 1GB
IntroThe GeForce GTX Titan Black makes use of a 28 nm design. nVidia has set the core speed at 889 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this specific card. It features 2880 SPUs along with 240 Texture Address Units and 48 ROPs.Compare those specs to the Radeon HD 4890 1GB, which makes use of a 55 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory is set to run at a speed of 975 MHz on this particular card. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX Titan Black should be a lot faster than the Radeon HD 4890 1GB in general. (explain)
Texel RateThe GeForce GTX Titan Black should be much (approximately 433%) faster with regards to anisotropic filtering than the Radeon HD 4890 1GB. (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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
