Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce GT 440 3GB
IntroThe GeForce 8800 GT 256MB has core clock speeds of 600 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 memory. It features 112 SPUs as well as 56 TAUs and 16 ROPs.Compare those specs to the GeForce GT 440 3GB, which comes with a GPU core clock speed of 594 MHz, and 3072 MB of GDDR3 memory set to run at 900 MHz through a 192-bit bus. It also is comprised of 144 Stream Processors, 24 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 GT 256MB should perform a bit faster than the GeForce GT 440 3GB in general. (explain)
Texel RateThe GeForce 8800 GT 256MB will be a lot (about 136%) better at texture filtering than the GeForce GT 440 3GB. (explain)
Pixel RateThe GeForce GT 440 3GB will be quite a bit (about 49%) better at FSAA than the GeForce 8800 GT 256MB, and also able to handle higher screen resolutions while still performing well. (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 (in units of megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must 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 high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
