Compare any two graphics cards:
GeForce 810M vs GeForce 940M
IntroThe GeForce 810M uses a 28 nm design. nVidia has set the core speed at 738 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this model. It features 48 SPUs along with 8 TAUs and 4 ROPs.Compare all of that to the GeForce 940M, which makes use of a 28 nm design. nVidia has set the core frequency at 1072 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this specific card. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce 940M should be 11% quicker than the GeForce 810M in general, due to its greater data rate. (explain)
Texel RateThe GeForce 940M is much (about 336%) more effective at AF than the GeForce 810M. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 940M is superior to the GeForce 810M, by a large margin. (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 largest amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
