Compare any two graphics cards:
GeForce GTX Titan Black vs Radeon R5 M255
IntroThe GeForce GTX Titan Black makes use of a 28 nm design. nVidia has clocked the core speed at 889 MHz. The GDDR5 memory works at a speed of 1750 MHz on this specific card. It features 2880 SPUs along with 240 Texture Address Units and 48 Rasterization Operator Units.Compare those specifications to the Radeon R5 M255, which comes with core speeds of 940 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the GeForce GTX Titan Black should be much faster than the Radeon R5 M255 overall. (explain)
Texel RateThe GeForce GTX Titan Black should be a lot (about 1035%) better at AF than the Radeon R5 M255. (explain)
Pixel RateIf using 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core 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 maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
