Compare any two graphics cards:
GeForce 8800 GS vs GeForce GT 440 1.5GB
IntroThe GeForce 8800 GS has a clock frequency of 550 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 192-bit bus, and makes use of a 65 nm design. It is made up of 96 SPUs, 48 Texture Address Units, and 12 Raster Operation Units.Compare all of that to the GeForce GT 440 1.5GB, which features a clock frequency of 594 MHz and a GDDR3 memory speed of 900 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It is comprised of 144 SPUs, 24 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GT 440 1.5GB should be just a bit faster than the GeForce 8800 GS overall. (explain)
Texel RateThe GeForce 8800 GS is much (about 85%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 440 1.5GB is superior to the GeForce 8800 GS, by far. (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 past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
