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

Theoretically speaking, the GeForce RTX 3080 Ti should be 104% faster than the GeForce RTX 2070 overall, because of its higher 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 a lot (more or less 115%) faster with regards to 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

If using a high screen resolution is important to you, then the GeForce RTX 3080 Ti is the winner, and very much so. (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 megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
