Compare any two graphics cards:
GeForce 930M vs GeForce GT 130
IntroThe GeForce 930M features a GPU core clock speed of 928 MHz, and the 2048 MB of DDR3 RAM runs at 900 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.Compare all of that to the GeForce GT 130, which features a GPU core clock speed of 500 MHz, and 768 MB of DDR2 RAM running at 250 MHz through a 192-bit bus. It also features 48 Stream Processors, 24 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce 930M should be 20% faster than the GeForce GT 130 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce 930M should be much (more or less 86%) more effective at texture filtering than the GeForce GT 130. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 130 is the winner, though not by far. (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 (counted in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write 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 the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
