Compare any two graphics cards:
GeForce 8800 GT 512MB vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 8800 GT 512MB features a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also features 112 Stream Processors, 56 Texture Address Units, and 16 ROPs.Compare all that to the GeForce GT 240 GDDR5 1GB, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM runs at a frequency of 850 MHz on this specific model. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 8800 GT 512MB should in theory be a little bit superior to the GeForce GT 240 GDDR5 1GB in general. (explain)
Texel RateThe GeForce 8800 GT 512MB should be a lot (approximately 91%) more effective at texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe GeForce 8800 GT 512MB should be much (more or less 118%) better at full screen anti-aliasing than the GeForce GT 240 GDDR5 1GB, and should 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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
