Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce 9600 GT 512MB
IntroThe GeForce 8600 GT 512MB DDR2 features clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the GeForce 9600 GT 512MB, which comes with core clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 64 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 9600 GT 512MB should theoretically be quite a bit better than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce 9600 GT 512MB should be a lot (more or less 141%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce 9600 GT 512MB is much (about 141%) better at AA than the GeForce 8600 GT 512MB DDR2, and also will be able to handle 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: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied 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 the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
