GeForce RTX 3060 Ti		200 Watts
GeForce RTX 3080		320 Watts
	Difference: 120 Watts (60%)

Memory Bandwidth

In theory, the GeForce RTX 3080 will be -100% quicker than the GeForce RTX 3060 Ti in general, due to its higher bandwidth. (explain)

GeForce RTX 3080		778547 MB/sec
GeForce RTX 3060 Ti		(Unknown) MB/sec
	Difference: 778547 (-100%)

Texel Rate

The GeForce RTX 3080 is quite a bit (approximately 83%) better at AF than the GeForce RTX 3060 Ti. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 3060 Ti		214320 Mtexels/sec
	Difference: 177360 (83%)

Pixel Rate

The GeForce RTX 3080 is a lot (more or less 23%) faster with regards to anti-aliasing than the GeForce RTX 3060 Ti, and also will be able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 3080		138240 Mpixels/sec
GeForce RTX 3060 Ti		112800 Mpixels/sec
	Difference: 25440 (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 transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
