Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 780 Ti should perform just a bit faster than the GeForce GTX Titan in general. (explain)

GeForce GTX 780 Ti		336000 MB/sec
GeForce GTX Titan		288384 MB/sec
	Difference: 47616 (17%)

Texel Rate

The GeForce GTX 780 Ti will be just a bit (more or less 12%) faster with regards to texture filtering than the GeForce GTX Titan. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 22512 (12%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 780 Ti is a better choice, but only just. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 1824 (5%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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