Compare any two graphics cards:
GeForce 8400 GS 512MB vs GeForce 9600 GT 1GB
IntroThe GeForce 8400 GS 512MB features a GPU core speed of 650 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 64-bit bus. It also is made up of 16 SPUs, 8 TAUs, and 4 Raster Operation Units.Compare those specifications to the GeForce 9600 GT 1GB, which comes with clock speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 64 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9600 GT 1GB should theoretically be quite a bit faster than the GeForce 8400 GS 512MB in general. (explain)
Texel RateThe GeForce 9600 GT 1GB will be a lot (about 300%) more effective at AF than the GeForce 8400 GS 512MB. (explain)
Pixel RateThe GeForce 9600 GT 1GB will be much (more or less 300%) more effective at anti-aliasing than the GeForce 8400 GS 512MB, and will be able to handle higher screen resolutions without losing too much performance. (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 max amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to reach the maximum fill rate.
