Compare any two graphics cards:
GeForce 930M vs GeForce GT 320
IntroThe GeForce 930M comes with a GPU core clock speed of 928 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.Compare all of that to the GeForce GT 320, which features core speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 RAM. It features 72 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the GeForce GT 320 should in theory be a lot superior to the GeForce 930M in general. (explain)
Texel RateThe GeForce 930M is much (about 72%) better at texture filtering than the GeForce GT 320. (explain)
Pixel RateThe GeForce 930M will be quite a bit (approximately 72%) faster with regards to FSAA than the GeForce GT 320, and also should be able to handle higher resolutions more effectively. (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 max amount of data (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core 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 applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
