GeForce GTX 965M		60 Watts
GeForce 8800 GS		105 Watts
	Difference: 45 Watts (75%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 965M should perform quite a bit faster than the GeForce 8800 GS in general. (explain)

GeForce GTX 965M		64000 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce GTX 965M is a lot (approximately 129%) better at anisotropic filtering than the GeForce 8800 GS. (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 34016 (129%)

Pixel Rate

The GeForce GTX 965M is much (approximately 358%) more effective at anti-aliasing than the GeForce 8800 GS, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 23608 (358%)

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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
