Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 130 Watts (108%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER will be 72% faster than the GeForce GTX 1660 Ti in general, due to its greater data rate. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 212992 (72%)

Texel Rate

The GeForce RTX 2080 SUPER is much (approximately 120%) faster with regards to texture filtering than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 172800 (120%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is superior to the GeForce GTX 1660 Ti, and very much so. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 33600 (47%)

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 largest amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
