Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970		145 Watts
GeForce RTX 2070 Super		215 Watts
	Difference: 70 Watts (48%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2070 Super should be quite a bit faster than the GeForce GTX 970 overall. (explain)

GeForce RTX 2070 Super		458752 MB/sec
GeForce GTX 970		224000 MB/sec
	Difference: 234752 (105%)

Texel Rate

The GeForce RTX 2070 Super will be much (about 135%) more effective at texture filtering than the GeForce GTX 970. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 147600 (135%)

Pixel Rate

The GeForce RTX 2070 Super is quite a bit (more or less 53%) faster with regards to FSAA than the GeForce GTX 970, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 35520 (53%)

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

Pixel Rate: Pixel rate is the most 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 number of Raster Operations Pipelines by the the card's 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
