GeForce RTX 2080 Ti		250 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

The GeForce RTX 3080 Ti should in theory perform quite a bit faster than the GeForce RTX 2080 Ti overall. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce RTX 2080 Ti		630784 MB/sec
	Difference: 303513 (48%)

Texel Rate

The GeForce RTX 3080 Ti should be a little bit (about 19%) more effective at texture filtering than the GeForce RTX 2080 Ti. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 2080 Ti		367200 Mtexels/sec
	Difference: 69600 (19%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce RTX 2080 Ti, by far. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 34080 (29%)

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 (in units of MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 can be processed in one second. This is calculated by multiplying the total number of texture units 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends 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.
