GeForce 8800 GTS (G92)		135 Watts
	Difference: 19 Watts (16%)

Memory Bandwidth

In theory, the GeForce GTX 550 Ti should be 59% quicker than the GeForce 8800 GTS (G92) in general, because of its greater bandwidth. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 36416 (59%)

Texel Rate

The GeForce 8800 GTS (G92) should be much (approximately 44%) more effective at AF than the GeForce GTX 550 Ti. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 12800 (44%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 550 Ti is a better choice, by far. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 11200 (108%)

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: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the 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 maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
