GeForce GTX 780 Ti		10900 points
	Difference: 766 (7%)

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX Titan Black should be a small bit (more or less 2%) faster with regards to texture filtering than the GeForce GTX 780 Ti. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 780 Ti		210000 Mtexels/sec
	Difference: 3360 (2%)

Pixel Rate

The GeForce GTX Titan Black will be a small bit (approximately 2%) more effective at anti-aliasing than the GeForce GTX 780 Ti, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 672 (2%)

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 information (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
