Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 8800 GTS (G80) 640MB uses a 90 nm design. nVidia has set the core speed at 513 MHz. The GDDR3 RAM is set to run at a speed of 792 MHz on this particular model. It features 96 SPUs as well as 48 TAUs and 20 Rasterization Operator Units.Compare those specs to the GeForce GT 240 GDDR5 1GB, which uses a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 memory runs at a frequency of 850 MHz on this particular model. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GTS (G80) 640MB, in theory, should perform a bit faster than the GeForce GT 240 GDDR5 1GB in general. (explain)
Texel RateThe GeForce 8800 GTS (G80) 640MB is a lot (about 40%) more effective at texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 8800 GTS (G80) 640MB is a better choice, by a large margin. (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 information (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
