Compare any two graphics cards:
GeForce 8500 GT vs GeForce 930M
IntroThe GeForce 8500 GT comes with a core clock speed of 450 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit memory bus, and uses a 80 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare those specs to the GeForce 930M, which makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The DDR3 RAM runs at a speed of 900 MHz on this specific card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce 930M should be a bit faster than the GeForce 8500 GT in general. (explain)
Texel RateThe GeForce 930M is a lot (about 519%) better at anisotropic filtering than the GeForce 8500 GT. (explain)
Pixel RateThe GeForce 930M will be much (more or less 312%) better at full screen anti-aliasing than the GeForce 8500 GT, and should be capable of handling higher screen resolutions better. (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 maximum amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
