GeForce GTX 1660 Ti vs GeForce RTX 2080 Ti

Intro

Compare all of that to the GeForce RTX 2080 Ti, which comes with GPU clock speed of 1350 MHz, and 11264 MB of GDDR6 memory running at 1750 MHz through a 352-bit bus. It also is comprised of 4352 SPUs, 272 TAUs, and 88 Raster Operation Units.

GeForce RTX 2080 Ti		250 Watts
	Difference: 130 Watts (108%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 2080 Ti should theoretically be much superior to the GeForce GTX 1660 Ti in general. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 335872 (114%)

Texel Rate

The GeForce RTX 2080 Ti should be much (about 155%) better at AF than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 223200 (155%)

Pixel Rate

The GeForce RTX 2080 Ti is quite a bit (more or less 65%) faster with regards to AA than the GeForce GTX 1660 Ti, and also will be capable of handling higher resolutions better. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 46800 (65%)

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 maximum amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour 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 fill 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 get to the maximum fill rate.
