Compare any two graphics cards:
GeForce GTX Titan Black vs Radeon HD 3690/3830
IntroThe GeForce GTX Titan Black makes use of a 28 nm design. nVidia has set the core frequency at 889 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this specific model. It features 2880 SPUs as well as 240 Texture Address Units and 48 ROPs.Compare those specs to the Radeon HD 3690/3830, which uses a 55 nm design. AMD has clocked the core frequency at 668 MHz. The GDDR3 RAM is set to run at a frequency of 828 MHz on this model. It features 320(64x5) SPUs as well as 16 TAUs and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX Titan Black will be 1168% quicker than the Radeon HD 3690/3830 in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX Titan Black should be a lot (about 1896%) more effective at texture filtering than the Radeon HD 3690/3830. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX Titan Black is the winner, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
