Geforce GTX 670		170 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 80 Watts (47%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER is 165% faster than the Geforce GTX 670 in general, because of its higher bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Geforce GTX 670		192000 MB/sec
	Difference: 315904 (165%)

Texel Rate

The GeForce RTX 2080 SUPER should be quite a bit (about 209%) faster with regards to texture filtering than the Geforce GTX 670. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Geforce GTX 670		102480 Mtexels/sec
	Difference: 214320 (209%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is superior to the Geforce GTX 670, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Geforce GTX 670		29280 Mpixels/sec
	Difference: 76320 (261%)

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 transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
