Compare any two graphics cards:
GeForce 920M vs GeForce GTX 1080
IntroThe GeForce 920M comes with a clock frequency of 954 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 32 Texture Address Units, and 8 ROPs.
Compare all that to the GeForce GTX 1080, which makes use of a 16 nm design. nVidia has clocked the core frequency at 1607 MHz. The GDDR5X memory works at a speed of 1251 MHz on this card. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks
The GeForce GTX 1080 should theoretically be a lot faster than the GeForce 920M in general. (explain)
Texel RateThe GeForce GTX 1080 should be a lot (approximately 742%) more effective at AF than the GeForce 920M. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 1080 is superior to the GeForce 920M, 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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 ability to reach the max fill rate.
