Compare any two graphics cards:
GeForce 830M vs GeForce 930M
IntroThe GeForce 830M comes with a GPU core speed of 1029 MHz, and the 2048 MB of DDR3 RAM runs at 900 MHz through a 64-bit bus. It also is comprised of 256 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare all that to the GeForce 930M, which makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this card. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateThe GeForce 930M should be quite a bit (approximately 35%) faster with regards to texture filtering than the GeForce 830M. (explain)
Pixel RateThe GeForce 830M will be a little bit (approximately 11%) faster with regards to AA than the GeForce 930M, and also should be able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate 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 filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
