Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs GeForce 930M
IntroThe GeForce 8600 GT 256MB DDR2 features a GPU core clock speed of 540 MHz, and the 256 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 ROPs.Compare those specs to the GeForce 930M, which features a GPU core clock speed of 928 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 64-bit bus. It also features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce 930M will be 13% faster than the GeForce 8600 GT 256MB DDR2 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce 930M should be quite a bit (about 158%) faster with regards to texture filtering than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateIf using 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 max amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
