Texel Rate

The GeForce RTX 2080 SUPER is a lot (approximately 56%) faster with regards to anisotropic 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

If using a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is a better choice, though only just barely. (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 megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
