Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070		175 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 175 Watts (100%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti should be 104% quicker than the GeForce RTX 2070 in general, due to its greater data rate. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce RTX 2070		458752 MB/sec
	Difference: 475545 (104%)

Texel Rate

The GeForce RTX 3080 Ti should be quite a bit (more or less 115%) better at texture filtering than the GeForce RTX 2070. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 233760 (115%)

Pixel Rate

The GeForce RTX 3080 Ti should be quite a bit (about 69%) faster with regards to AA than the GeForce RTX 2070, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 62640 (69%)

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 max amount of information (in units of 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 speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 can be processed per second. This number is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour 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 rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
