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

Theoretically speaking, the GeForce GTX 550 Ti should be 71% quicker than the GeForce 8800 GT 1GB in general, because of 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 is a small bit (approximately 17%) faster with regards to 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 running with a high resolution is important to you, then the GeForce GTX 550 Ti is superior to the GeForce 8800 GT 1GB, 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: Bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
