GeForce GTX 980 Ti		336000 MB/sec
	Difference: 122752 (37%)

Texel Rate

The GeForce RTX 2070 Super should be a lot (about 46%) faster with regards to texture filtering than the GeForce GTX 980 Ti. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 80800 (46%)

Pixel Rate

The GeForce RTX 2070 Super is just a bit (about 7%) better at full screen anti-aliasing than the GeForce GTX 980 Ti, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
GeForce GTX 980 Ti		96000 Mpixels/sec
	Difference: 6720 (7%)

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 (counted in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
