Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black should be 209% quicker than the GeForce GTX 460 SE overall, because of its greater data rate. (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 is much (more or less 584%) more effective at anisotropic filtering 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

The GeForce GTX Titan Black is much (more or less 105%) more effective at FSAA than the GeForce GTX 460 SE, and also should be able to handle higher resolutions without losing too much performance. (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 largest amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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 quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
