GeForce RTX 3070		220 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 30 Watts (14%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER should perform just a bit faster than the GeForce RTX 3070 in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 507904 (-100%)

Texel Rate

The GeForce RTX 2080 SUPER is just a bit (more or less 15%) faster with regards to anisotropic filtering than the GeForce RTX 3070. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 40800 (15%)

Pixel Rate

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

GeForce RTX 3070		144000 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 38400 (36%)

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 moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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