Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce 9800 GT 1GB
IntroThe GeForce 8800 GTS (G80) 640MB comes with a GPU core speed of 513 MHz, and the 640 MB of GDDR3 memory runs at 792 MHz through a 320-bit bus. It also features 96 SPUs, 48 Texture Address Units, and 20 Raster Operation Units.Compare all that to the GeForce 9800 GT 1GB, which features a GPU core clock speed of 600 MHz, and 1024 MB of GDDR3 RAM set to run at 900 MHz through a 256-bit bus. It also features 112 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GTS (G80) 640MB should theoretically be a bit superior to the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe GeForce 9800 GT 1GB should be much (about 36%) faster with regards to anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 8800 GTS (G80) 640MB is superior to the GeForce 9800 GT 1GB, though only just barely. (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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
