Compare any two graphics cards:
GeForce 8500 GT vs GeForce GT 310
IntroThe GeForce 8500 GT makes use of a 80 nm design. nVidia has clocked the core speed at 450 MHz. The DDR2 RAM is set to run at a speed of 400 MHz on this specific model. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.Compare all that to the GeForce GT 310, which features a clock speed of 589 MHz and a DDR2 memory speed of 1000 MHz. It also features a 64-bit bus, and uses a 40 nm design. It is made up of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 310 should be much faster than the GeForce 8500 GT in general. (explain)
Texel RateThe GeForce GT 310 will be much (more or less 31%) better at texture filtering than the GeForce 8500 GT. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 310 is a better choice, 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 data (measured in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 applied in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
