Compare any two graphics cards:
GeForce 8800 GS vs GeForce GT 220 GDDR3
IntroThe GeForce 8800 GS has a GPU clock speed of 550 MHz, and the 384 MB of GDDR3 RAM is set to run at 800 MHz through a 192-bit bus. It also is made up of 96 Stream Processors, 48 TAUs, and 12 Raster Operation Units.Compare those specs to the GeForce GT 220 GDDR3, which features a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 memory running at 1012 MHz through a 128-bit bus. It also is comprised of 48 Stream Processors, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce 8800 GS should perform a small bit faster than the GeForce GT 220 GDDR3 overall. (explain)
Texel RateThe GeForce 8800 GS should be quite a bit (more or less 164%) faster with regards to anisotropic filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 8800 GS is the winner, by a large margin. (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 data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
