	Difference: 49152 (17%)

Texel Rate

The GeForce RTX 2060 is a bit (about 14%) more effective at texture filtering than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 2060		163800 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 19800 (14%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 1660 Ti is the winner, but only just. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 6480 (10%)

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 (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
