Compare any two graphics cards:
GeForce GTX 750 Ti vs GeForce GTX 870M
IntroThe GeForce GTX 750 Ti features core clock speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.Compare all that to the GeForce GTX 870M, which features a core clock frequency of 941 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 192-bit bus, and makes use of a 28 nm design. It is made up of 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 870M should in theory be a little bit better than the GeForce GTX 750 Ti in general. (explain)
Texel RateThe GeForce GTX 870M will be much (approximately 158%) better at texture filtering than the GeForce GTX 750 Ti. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 870M is a better choice, 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 max amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total 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 per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
