Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti		116 Watts
GeForce GTX 285 2GB		204 Watts
	Difference: 88 Watts (76%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 2GB should be quite a bit faster than the GeForce GTX 550 Ti in general. (explain)

GeForce GTX 285 2GB		158976 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 60480 (61%)

Texel Rate

The GeForce GTX 285 2GB is quite a bit (approximately 80%) more effective at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 285 2GB		51840 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 23040 (80%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 550 Ti is superior to the GeForce GTX 285 2GB, not by a very large margin though. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce GTX 285 2GB		20736 Mpixels/sec
	Difference: 864 (4%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
