Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3060		170 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 80 Watts (47%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3060 is 10% quicker than the GeForce GTX 780 Ti overall, because of its higher bandwidth. (explain)

GeForce RTX 3060		368640 MB/sec
GeForce GTX 780 Ti		336000 MB/sec
	Difference: 32640 (10%)

Texel Rate

The GeForce GTX 780 Ti should be a lot (more or less 42%) faster with regards to texture filtering than the GeForce RTX 3060. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce RTX 3060		147840 Mtexels/sec
	Difference: 62160 (42%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 3060 is a better choice, by a large margin. (explain)

GeForce RTX 3060		63360 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 21360 (51%)

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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher 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 video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
