Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070		175 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER is 11% quicker than the GeForce RTX 2070 in general, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce RTX 2080 SUPER should be a lot (about 56%) more effective at texture filtering than the GeForce RTX 2070. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 113760 (56%)

Pixel Rate

The GeForce RTX 2080 SUPER will be a small bit (about 17%) more effective at full screen anti-aliasing than the GeForce RTX 2070, and should be able to handle higher resolutions better. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 15360 (17%)

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 max amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
