GeForce 8800 Ultra		171 Watts
	Difference: 61 Watts (55%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 Ultra will be 20% faster than the GeForce GTX 650 Ti 2GB overall, due to its greater data rate. (explain)

GeForce 8800 Ultra		103680 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 17280 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be a lot (about 52%) faster with regards to AF than the GeForce 8800 Ultra. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 20224 (52%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 650 Ti 2GB is a better choice, though only just barely. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 160 (1%)

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 information (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 number is calculated by multiplying the total number of texture units of the card by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
