GeForce RTX 3070 Ti		290 Watts
	Difference: 170 Watts (142%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 3070 Ti should in theory be quite a bit superior to the GeForce GTX 1660 Ti in general. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 327987 (111%)

Texel Rate

The GeForce RTX 3070 Ti should be quite a bit (approximately 110%) faster with regards to AF than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 158400 (110%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3070 Ti is the winner, and very much so. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 79200 (110%)

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 (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
