Compare any two graphics cards:
GeForce 930M vs GeForce GTX 850M
IntroThe GeForce 930M comes with a clock frequency of 928 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 ROPs.Compare all that to the GeForce GTX 850M, which makes use of a 28 nm design. nVidia has set the core frequency at 876 MHz. The DDR3 memory runs at a speed of 1000 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the GeForce GTX 850M should in theory be much superior to the GeForce 930M in general. (explain)
Texel RateThe GeForce GTX 850M is a lot (more or less 57%) faster with regards to anisotropic filtering than the GeForce 930M. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 850M 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 data (in units of MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
