Compare any two graphics cards:

GeForce GTX 1060 vs GeForce GTX 1660 Ti

Intro

The GeForce GTX 1060 features a core clock frequency of 1506 MHz and a GDDR5 memory speed of 2000 MHz. It also makes use of a 192-bit bus, and uses a 16 nm design. It is made up of 1280 SPUs, 80 Texture Address Units, and 48 Raster Operation Units.

Compare all of that to the GeForce GTX 1660 Ti, which makes use of a 12 nm design. nVidia has set the core speed at 1500 MHz. The GDDR6 memory is set to run at a frequency of 1500 MHz on this specific card. It features 1536 SPUs along with 96 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the GeForce GTX 1660 Ti should in theory be much better than the GeForce GTX 1060 in general. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
GeForce GTX 1060		196608 MB/sec
	Difference: 98304 (50%)

Texel Rate

The GeForce GTX 1660 Ti will be a bit (more or less 20%) more effective at anisotropic filtering than the GeForce GTX 1060. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce GTX 1060		120480 Mtexels/sec
	Difference: 23520 (20%)

Pixel Rate

The GeForce GTX 1060 is a small bit (more or less 0%) faster with regards to anti-aliasing than the GeForce GTX 1660 Ti, and also able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1060		72288 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 288 (0%)

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.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video 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 the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
