GeForce GTX 1660 Ti vs GeForce RTX 2060

Intro

Compare those specs to the GeForce RTX 2060, which comes with a GPU core clock speed of 1365 MHz, and 6144 MB of GDDR6 memory set to run at 1750 MHz through a 192-bit bus. It also is made up of 1920 Stream Processors, 120 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
GeForce RTX 2060		160 Watts
	Difference: 40 Watts (33%)

Memory Bandwidth

The GeForce RTX 2060 should in theory perform just a bit faster than the GeForce GTX 1660 Ti in general. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 49152 (17%)

Texel Rate

The GeForce RTX 2060 should be a small bit (approximately 14%) more effective at AF 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 lots of anti-aliasing is important to you, then the GeForce GTX 1660 Ti is superior to the GeForce RTX 2060, not by a very large margin though. (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: Bandwidth is the max amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
