Compare any two graphics cards:
GeForce GTX 850M vs Nvidia Titan X
IntroThe GeForce GTX 850M has a GPU core clock speed of 876 MHz, and the 2048 MB of DDR3 memory runs at 1000 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 ROPs.Compare that to the Nvidia Titan X, which features a GPU core clock speed of 1417 MHz, and 12288 MB of GDDR5X memory running at 1251 MHz through a 384-bit bus. It also is made up of 3584 Stream Processors, 224 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Nvidia Titan X should theoretically be much superior to the GeForce GTX 850M overall. (explain)
Texel RateThe Nvidia Titan X should be quite a bit (more or less 806%) better at texture filtering than the GeForce GTX 850M. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Nvidia Titan X is the winner, 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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
