Compare any two graphics cards:
GeForce 930M vs GeForce 9500 GT DDR2
IntroThe GeForce 930M makes use of a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The DDR3 memory runs at a speed of 900 MHz on this specific model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.Compare that to the GeForce 9500 GT DDR2, which comes with GPU core speed of 550 MHz, and 256 MB of DDR2 memory running at 500 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce 9500 GT DDR2 should be 11% quicker than the GeForce 930M in general, because of its higher data rate. (explain)
Texel RateThe GeForce 930M is much (approximately 153%) faster with regards to AF than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce 930M should be quite a bit (more or less 69%) better at anti-aliasing than the GeForce 9500 GT DDR2, and should be able to handle higher screen resolutions without slowing down too much. (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 transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
