Compare any two graphics cards:
GeForce 920M vs GeForce GTX 1080
IntroThe GeForce 920M uses a 28 nm design. nVidia has set the core frequency at 954 MHz. The DDR3 RAM runs at a speed of 900 MHz on this specific model. It features 384 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.
Compare all that to the GeForce GTX 1080, which comes with GPU core speed of 1607 MHz, and 8192 MB of GDDR5X RAM running at 1251 MHz through a 256-bit bus. It also is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks
Performance-wise, the GeForce GTX 1080 should theoretically be quite a bit superior to the GeForce 920M overall. (explain)
Texel RateThe GeForce GTX 1080 should be much (approximately 742%) faster with regards to AF than the GeForce 920M. (explain)
Pixel RateThe GeForce GTX 1080 is much (approximately 1248%) more effective at anti-aliasing than the GeForce 920M, and also will be able to handle higher screen resolutions while still performing well. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
