Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 780 Ti will be 17% quicker than the Geforce GTX 780 overall, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GTX 780 Ti should be quite a bit (more or less 27%) faster with regards to AF than the Geforce GTX 780. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 44304 (27%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 780 Ti is superior to the Geforce GTX 780, but only just. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 576 (1%)

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 MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum 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 clock speed of the chip. The better this number, the better the graphics 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 the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
