Compare any two graphics cards:
GeForce 8800 GTX vs GeForce GTX 465
IntroThe GeForce 8800 GTX comes with a GPU core speed of 575 MHz, and the 768 MB of GDDR3 memory is set to run at 900 MHz through a 384-bit bus. It also is comprised of 128 SPUs, 64 TAUs, and 24 Raster Operation Units.Compare those specs to the GeForce GTX 465, which uses a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 RAM works at a speed of 802 MHz on this specific card. It features 352 SPUs along with 44 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 465 should theoretically be a small bit better than the GeForce 8800 GTX overall. (explain)
Texel RateThe GeForce 8800 GTX should be quite a bit (approximately 38%) faster with regards to anisotropic filtering than the GeForce GTX 465. (explain)
Pixel RateThe GeForce GTX 465 should be quite a bit (more or less 41%) faster with regards to anti-aliasing than the GeForce 8800 GTX, and should be capable of handling higher resolutions without losing too much performance. (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 largest amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling 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 can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
