Compare any two graphics cards:
GeForce 810M vs GeForce GTX 660
IntroThe GeForce 810M comes with a core clock speed of 738 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It features 48 SPUs, 8 TAUs, and 4 ROPs.Compare those specs to the GeForce GTX 660, which comes with a core clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 192-bit bus, and makes use of a 28 nm design. It features 960 SPUs, 80 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 660 will be 901% quicker than the GeForce 810M overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 660 is quite a bit (more or less 1228%) better at texture filtering than the GeForce 810M. (explain)
Pixel RateThe GeForce GTX 660 should be quite a bit (approximately 697%) more effective at FSAA than the GeForce 810M, and also should be capable of handling higher resolutions better. (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 (measured in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
