Compare any two graphics cards:
GeForce 920M vs GeForce GTX 1080
IntroThe GeForce 920M features core speeds of 954 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 32 TAUs and 8 ROPs.
Compare all that to the GeForce GTX 1080, which features a clock speed of 1607 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 256-bit memory bus, and makes use of a 16 nm design. It features 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks
As far as performance goes, the GeForce GTX 1080 should theoretically be quite a bit superior to the GeForce 920M in general. (explain)
Texel RateThe GeForce GTX 1080 will be much (more or less 742%) better at anisotropic filtering than the GeForce 920M. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 1080 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.
GeForce GTX 1080
Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
