Compare any two graphics cards:
GeForce 8500 GT vs GeForce GT 310
IntroThe GeForce 8500 GT has a GPU core speed of 450 MHz, and the 512 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also is made up of 16 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.Compare that to the GeForce GT 310, which makes use of a 40 nm design. nVidia has clocked the core frequency at 589 MHz. The DDR2 memory is set to run at a speed of 1000 MHz on this specific model. It features 16 SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 310 should in theory be quite a bit superior to the GeForce 8500 GT overall. (explain)
Texel RateThe GeForce GT 310 is quite a bit (about 31%) more effective at anisotropic filtering than the GeForce 8500 GT. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GT 310 is superior to the GeForce 8500 GT, 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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock 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 applied in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
