Compare any two graphics cards:
GeForce 830M vs GeForce 8500 GT
IntroThe GeForce 830M uses a 28 nm design. nVidia has clocked the core frequency at 1029 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 256 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specs to the GeForce 8500 GT, which comes with a clock frequency of 450 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 128-bit memory bus, and uses a 80 nm design. It features 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 830M should perform just a bit faster than the GeForce 8500 GT overall. (explain)
Texel RateThe GeForce 830M should be much (approximately 357%) better at anisotropic filtering than the GeForce 8500 GT. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 830M is the winner, and very much so. (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 (counted in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
