Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce GT 230
IntroThe GeForce 8800 GT 256MB has a core clock speed of 600 MHz and a GDDR3 memory frequency of 700 MHz. It also features a 256-bit memory bus, and uses a 65 nm design. It is made up of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.Compare all that to the GeForce GT 230, which features a clock speed of 550 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 192-bit bus, and uses a 40 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GT 256MB, in theory, should be a small bit faster than the GeForce GT 230 overall. (explain)
Texel RateThe GeForce 8800 GT 256MB should be quite a bit (more or less 282%) more effective at anisotropic filtering than the GeForce GT 230. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 8800 GT 256MB is the winner, by far. (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 information (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
