Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce 9800 GT 1GB
IntroThe GeForce 8800 GT 1GB uses a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular model. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare those specifications to the GeForce 9800 GT 1GB, which comes with a clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit memory bus, and uses a 65/55 nm design. It features 112 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)
Texel RateBoth cards have exactly the same texel fill rate, so in theory they should perform equally good at at AF. (explain)Pixel RateBoth cards have the exact same pixel fill rate, so theoretically they should be equally good at at full screen anti-aliasing, and be capable of handling the same resolutions. (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 maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 get to the max fill rate.
