Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce GTS 250 512MB
IntroThe GeForce 8800 GTS (G80) 640MB comes with a GPU core speed of 513 MHz, and the 640 MB of GDDR3 memory runs at 792 MHz through a 320-bit bus. It also is made up of 96 Stream Processors, 48 TAUs, and 20 Raster Operation Units.Compare all of that to the GeForce GTS 250 512MB, which has GPU core speed of 738 MHz, and 512 MB of GDDR3 memory running at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 250 512MB should theoretically perform a bit faster than the GeForce 8800 GTS (G80) 640MB in general. (explain)
Texel RateThe GeForce GTS 250 512MB is much (about 92%) faster with regards to texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTS 250 512MB is superior to the GeForce 8800 GTS (G80) 640MB, but only just. (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 (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen 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 number of texture units 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 in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
