GeForce GTX 465		102592 MB/sec
	Difference: 9408 (9%)

Texel Rate

The GeForce GTX 960 will be much (approximately 170%) more effective at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 45420 (170%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 960 is superior to the GeForce GTX 465, by far. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 16640 (86%)

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 largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics 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 Render Output Units by the the core speed of the card. 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
