Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti should be 40% faster than the Radeon RX 470 4GB in general, because of its higher bandwidth. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 83712 (40%)

Texel Rate

The GeForce GTX 1660 Ti should be a lot (about 21%) more effective at anisotropic filtering than the Radeon RX 470 4GB. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 25472 (21%)

Pixel Rate

The GeForce GTX 1660 Ti should be a lot (more or less 143%) better at anti-aliasing than the Radeon RX 470 4GB, and also will be capable of handling higher screen resolutions better. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 42368 (143%)

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 data (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher 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 that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
