Power Consumption (Max TDP)

GeForce GTX 460 SE		150 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the GeForce GTX Titan Black should be 209% quicker than the GeForce GTX 460 SE overall, because of its higher bandwidth. (explain)

GeForce GTX Titan Black		336000 MB/sec
GeForce GTX 460 SE		108800 MB/sec
	Difference: 227200 (209%)

Texel Rate

The GeForce GTX Titan Black should be a lot (about 584%) better at AF than the GeForce GTX 460 SE. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 182160 (584%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan Black is a better choice, and very much so. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 21872 (105%)

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 max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
