Compare any two graphics cards:
GeForce 8800 GTX vs GeForce GT 340
IntroThe GeForce 8800 GTX has a GPU clock speed of 575 MHz, and the 768 MB of GDDR3 RAM is set to run at 900 MHz through a 384-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 24 ROPs.Compare that to the GeForce GT 340, which uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 memory is set to run at a speed of 850 MHz on this specific model. It features 96 SPUs as well as 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 8800 GTX should perform a lot faster than the GeForce GT 340 in general. (explain)
Texel RateThe GeForce 8800 GTX will be much (approximately 109%) better at AF than the GeForce GT 340. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 8800 GTX is a better choice, 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 data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units 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 processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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 - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
