GeForce RTX 2070 Super		215 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 35 Watts (16%)

Memory Bandwidth

The GeForce RTX 2080 SUPER should in theory be just a bit faster than the GeForce RTX 2070 Super overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce RTX 2070 Super		458752 MB/sec
	Difference: 49152 (11%)

Texel Rate

The GeForce RTX 2080 SUPER will be quite a bit (approximately 23%) more effective at AF than the GeForce RTX 2070 Super. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 60000 (23%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is a better choice, though not by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce RTX 2070 Super		102720 Mpixels/sec
	Difference: 2880 (3%)

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 (measured in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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