Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the Geforce GTX 780 should perform quite a bit faster than the GeForce GTX 480 in general. (explain)

Geforce GTX 780		288384 MB/sec
GeForce GTX 480		177408 MB/sec
	Difference: 110976 (63%)

Texel Rate

The Geforce GTX 780 should be a lot (approximately 295%) faster with regards to AF than the GeForce GTX 480. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 123696 (295%)

Pixel Rate

If using high levels of AA is important to you, then the Geforce GTX 780 is a better choice, by far. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce GTX 480		33600 Mpixels/sec
	Difference: 7824 (23%)

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 maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
