Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB		110 Watts
GeForce 8800 GTS (G80) 320MB		143 Watts
	Difference: 33 Watts (30%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti 2GB should be 36% faster than the GeForce 8800 GTS (G80) 320MB in general, because of its higher data rate. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
GeForce 8800 GTS (G80) 320MB		63360 MB/sec
	Difference: 23040 (36%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be a lot (more or less 141%) faster with regards to AF than the GeForce 8800 GTS (G80) 320MB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
	Difference: 34768 (141%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti 2GB is the winner, by a large margin. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
	Difference: 4588 (45%)

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 (measured in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the 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 the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
