Compare any two graphics cards:
GeForce 825M vs GeForce 920M
IntroThe GeForce 825M features a GPU core speed of 850 MHz, and the 2048 MB of DDR3 RAM is set to run at 900 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 16 Texture Address Units, and 8 ROPs.Compare all of that to the GeForce 920M, which uses a 28 nm design. nVidia has set the core speed at 954 MHz. The DDR3 RAM works at a speed of 900 MHz on this specific model. It features 384 SPUs along with 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have the exact same bandwidth, so theoretically they should perform exactly the same. (explain)
Texel RateThe GeForce 920M will be much (more or less 124%) better at texture filtering than the GeForce 825M. (explain)
Pixel RateThe GeForce 920M should be a bit (more or less 12%) faster with regards to anti-aliasing than the GeForce 825M, and should be able to handle higher resolutions more effectively. (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 information (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number 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 calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
