Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce GTX 470
IntroThe GeForce 8800 GT 1GB comes with a core clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and uses a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 ROPs.Compare all that to the GeForce GTX 470, which uses a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 RAM works at a frequency of 837 MHz on this particular card. It features 448 SPUs along with 56 Texture Address Units and 40 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 470 should perform quite a bit faster than the GeForce 8800 GT 1GB in general. (explain)
Texel RateThe GeForce GTX 470 should be a bit (more or less 1%) better at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)
Pixel RateThe GeForce GTX 470 should be much (approximately 153%) better at anti-aliasing than the GeForce 8800 GT 1GB, and should be capable of handling higher resolutions without slowing down too much. (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 (counted in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
