Compare any two graphics cards:
GeForce GTX 1080 vs Radeon R9 M265X
IntroThe GeForce GTX 1080 comes with core clock speeds of 1607 MHz on the GPU, and 1251 MHz on the 8192 MB of GDDR5X RAM. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.Compare those specifications to the Radeon R9 M265X, which has clock speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce GTX 1080 should be 355% quicker than the Radeon R9 M265X in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 1080 should be much (about 1018%) better at anisotropic filtering than the Radeon R9 M265X. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 1080 is a better choice, by a large margin. (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 megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the max fill rate.
