Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB DDR2		47 Watts
GeForce GTX 965M		60 Watts
	Difference: 13 Watts (28%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 965M is 400% quicker than the GeForce 8600 GT 1GB DDR2 in general, because of its greater data rate. (explain)

GeForce GTX 965M		64000 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 51200 (400%)

Texel Rate

The GeForce GTX 965M is quite a bit (approximately 599%) better at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 51776 (599%)

Pixel Rate

The GeForce GTX 965M should be much (about 599%) more effective at full screen anti-aliasing than the GeForce 8600 GT 1GB DDR2, and capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 25888 (599%)

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 data (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
