GeForce GTX 960		120 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 460 2GB should theoretically be just a bit superior to the GeForce GTX 960 in general. (explain)

GeForce GTX 460 2GB		115200 MB/sec
GeForce GTX 960		112000 MB/sec
	Difference: 3200 (3%)

Texel Rate

The GeForce GTX 960 should be much (about 91%) faster with regards to anisotropic filtering than the GeForce GTX 460 2GB. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 34328 (91%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 960 is the winner, and very much so. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 14464 (67%)

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 across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 amount of texture units by the core speed of the chip. The higher this number, the better the 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 could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
