GeForce GTX 960M		64000 MB/sec
	Difference: 38592 (60%)

Texel Rate

The GeForce GTX 960M should be quite a bit (about 64%) more effective at texture filtering than the GeForce GTX 465. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 17132 (64%)

Pixel Rate

The GeForce GTX 465 is a small bit (about 11%) more effective at anti-aliasing than the GeForce GTX 960M, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GTX 960M		17536 Mpixels/sec
	Difference: 1888 (11%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
