Compare any two graphics cards:
GeForce 8600 GT 1GB DDR2 vs GeForce 930M
IntroThe GeForce 8600 GT 1GB DDR2 has a GPU core speed of 540 MHz, and the 1024 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also features 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare that to the GeForce 930M, which has GPU core speed of 928 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce 930M is 13% quicker than the GeForce 8600 GT 1GB DDR2 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce 930M will be much (about 158%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 930M is a better choice, 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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
