GeForce RTX 3070 Ti		290 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 60 Watts (21%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 Ti is 50% faster than the GeForce RTX 3070 Ti in general, because of its higher bandwidth. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce RTX 3070 Ti		622899 MB/sec
	Difference: 311398 (50%)

Texel Rate

The GeForce RTX 3080 Ti is a lot (approximately 44%) faster with regards to texture filtering than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 134400 (44%)

Pixel Rate

The GeForce RTX 3080 Ti will be a little bit (more or less 1%) faster with regards to AA than the GeForce RTX 3070 Ti, and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 3070 Ti		151200 Mpixels/sec
	Difference: 1680 (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 data (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
