	Difference: 175 Watts (233%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER is 429% quicker than the GeForce GTX 970M overall, because of its greater bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 970M		96000 MB/sec
	Difference: 411904 (429%)

Texel Rate

The GeForce RTX 2080 SUPER will be a lot (more or less 329%) better at texture filtering than the GeForce GTX 970M. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 970M		73920 Mtexels/sec
	Difference: 242880 (329%)

Pixel Rate

The GeForce RTX 2080 SUPER will be quite a bit (about 138%) more effective at FSAA than the GeForce GTX 970M, and also will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 970M		44352 Mpixels/sec
	Difference: 61248 (138%)

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 maximum amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core 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 per 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 - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
