Compare any two graphics cards:
GeForce 940M vs GeForce GTX 870M
IntroThe GeForce 940M comes with a clock frequency of 1072 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.Compare those specs to the GeForce GTX 870M, which has clock speeds of 941 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 Texture Address Units and 24 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTX 870M, in theory, should be much faster than the GeForce 940M overall. (explain)
Texel RateThe GeForce GTX 870M will be a lot (more or less 310%) more effective at anisotropic filtering than the GeForce 940M. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 870M is superior to the GeForce 940M, by far. (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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
