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

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 8800 GTS (G80) 640MB will be 10% quicker than the GeForce 8800 GT 1GB overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce 8800 GT 1GB will be a lot (about 36%) more effective at anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 640MB will be a bit (about 7%) more effective at FSAA than the GeForce 8800 GT 1GB, and will be capable of handling higher screen resolutions while still performing well. (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 (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 can be processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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 reach the max fill rate.
