GeForce GTX 1660 Ti vs GeForce RTX 2080 SUPER

Intro

Compare all of that to the GeForce RTX 2080 SUPER, which comes with clock speeds of 1650 MHz on the GPU, and 1937 MHz on the 8192 MB of GDDR6 RAM. It features 3072 SPUs as well as 192 Texture Address Units and 64 ROPs.

	Difference: 212992 (72%)

Texel Rate

The GeForce RTX 2080 SUPER is quite a bit (more or less 120%) better at texture filtering than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 172800 (120%)

Pixel Rate

The GeForce RTX 2080 SUPER should be quite a bit (more or less 47%) faster with regards to AA than the GeForce GTX 1660 Ti, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 33600 (47%)

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 (in units of MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling 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 can possibly record to the local memory in one second - measured in millions of pixels per second. The number 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
