Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce GT 440 1.5GB
IntroThe GeForce 8800 GT 256MB has a core clock frequency of 600 MHz and a GDDR3 memory speed of 700 MHz. It also uses a 256-bit bus, and uses a 65 nm design. It features 112 SPUs, 56 Texture Address Units, and 16 ROPs.Compare that to the GeForce GT 440 1.5GB, which features core clock speeds of 594 MHz on the GPU, and 900 MHz on the 1536 MB of GDDR3 RAM. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 GT 256MB should be 4% quicker than the GeForce GT 440 1.5GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce 8800 GT 256MB is a lot (more or less 136%) faster with regards to AF than the GeForce GT 440 1.5GB. (explain)
Pixel RateThe GeForce GT 440 1.5GB will be a lot (about 49%) faster with regards to full screen anti-aliasing than the GeForce 8800 GT 256MB, and should be capable of handling higher screen resolutions more effectively. (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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write 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 core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
