Compare any two graphics cards:
GeForce GTX 1080 vs GeForce GTX 870M
IntroThe GeForce GTX 1080 has a GPU core clock speed of 1607 MHz, and the 8192 MB of GDDR5X memory runs at 1251 MHz through a 256-bit bus. It also is comprised of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.Compare those specs to the GeForce GTX 870M, which makes use of a 28 nm design. nVidia has set the core speed at 941 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific model. It features 1344 SPUs along with 112 TAUs and 24 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 1080, in theory, should be a lot faster than the GeForce GTX 870M in general. (explain)
Texel RateThe GeForce GTX 1080 should be quite a bit (approximately 144%) better at anisotropic filtering than the GeForce GTX 870M. (explain)
Pixel RateThe GeForce GTX 1080 is much (about 355%) faster with regards to anti-aliasing than the GeForce GTX 870M, and should be capable of handling 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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 is worked out 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
