Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB		110 Watts
GeForce GTX 960		120 Watts
	Difference: 10 Watts (9%)

Memory Bandwidth

In theory, the GeForce GTX 960 will be 30% faster than the GeForce GTX 650 Ti 2GB overall, due to its higher data rate. (explain)

GeForce GTX 960		112000 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 25600 (30%)

Texel Rate

The GeForce GTX 960 is much (about 21%) faster with regards to anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 12736 (21%)

Pixel Rate

The GeForce GTX 960 is quite a bit (more or less 143%) faster with regards to anti-aliasing than the GeForce GTX 650 Ti 2GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 21216 (143%)

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 (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at 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 could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
