Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 11 Watts (10%)

Memory Bandwidth

In theory, the GeForce GTX 550 Ti will be 71% quicker than the GeForce 8800 GT 1GB overall, due to its greater data rate. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 40896 (71%)

Texel Rate

The GeForce 8800 GT 1GB should be a little bit (about 17%) better at texture filtering than the GeForce GTX 550 Ti. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 4800 (17%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is the winner, and very much so. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 12000 (125%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This 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 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 card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
