Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce GTX 460
IntroThe GeForce 8800 GT 256MB features a GPU core clock speed of 600 MHz, and the 256 MB of GDDR3 memory is set to run at 700 MHz through a 256-bit bus. It also is comprised of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.Compare all of that to the GeForce GTX 460, which features GPU core speed of 675 MHz, and 768 MB of GDDR5 memory running at 900 MHz through a 192-bit bus. It also is comprised of 336 Stream Processors, 56 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 460 should theoretically be quite a bit better than the GeForce 8800 GT 256MB in general. (explain)
Texel RateThe GeForce GTX 460 will be a little bit (approximately 13%) more effective at AF than the GeForce 8800 GT 256MB. (explain)
Pixel RateThe GeForce GTX 460 should be much (more or less 69%) faster with regards to FSAA than the GeForce 8800 GT 256MB, and 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 data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If 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 high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
