Compare any two graphics cards:
GeForce 820M vs GeForce 930M
IntroThe GeForce 820M makes use of a 28 nm design. nVidia has set the core speed at 719 MHz. The DDR3 memory is set to run at a frequency of 1000 MHz on this card. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.Compare all of that to the GeForce 930M, which has GPU clock speed of 928 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 820M, in theory, should be a little bit faster than the GeForce 930M overall. (explain)
Texel RateThe GeForce 930M is a lot (more or less 94%) faster with regards to texture filtering than the GeForce 820M. (explain)
Pixel RateThe GeForce 930M is much (about 158%) better at FSAA than the GeForce 820M, and also capable of handling higher screen resolutions while still performing well. (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 data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels the video card could 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 ROPs by the the core clock speed. 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
