In theory, the GeForce RTX 2080 Ti should be 1% quicker than the GeForce RTX 3070 Ti overall, due to its greater data rate. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
GeForce RTX 3070 Ti		622899 MB/sec
	Difference: 7885 (1%)

Texel Rate

The GeForce RTX 2080 Ti is much (more or less 21%) more effective at anisotropic filtering than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 64800 (21%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3070 Ti is superior to the GeForce RTX 2080 Ti, by a large margin. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 32400 (27%)

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 (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
