Compare any two graphics cards:
GeForce GTX 870M vs Radeon R9 Nano
IntroThe GeForce GTX 870M features a clock speed of 941 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 192-bit memory bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 24 Raster Operation Units.Compare those specs to the Radeon R9 Nano, which has a core clock frequency of 1000 MHz and a HBM memory frequency of 500 MHz. It also uses a 4096-bit bus, and uses a 28 nm design. It features 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 Nano should perform a lot faster than the GeForce GTX 870M in general. (explain)
Texel RateThe Radeon R9 Nano will be much (about 143%) better at texture filtering than the GeForce GTX 870M. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R9 Nano is superior to the GeForce GTX 870M, 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 maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
