Compare any two graphics cards:
GeForce 810M vs GeForce 920M
IntroThe GeForce 810M has a core clock frequency of 738 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is made up of 48 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare all that to the GeForce 920M, which comes with a core clock speed of 954 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same memory bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe GeForce 920M is quite a bit (about 417%) better at texture filtering than the GeForce 810M. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 920M is the winner, and very much so. (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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
