GeForce GTX 1660 Ti vs GeForce RTX 2080

Intro

Compare all of that to the GeForce RTX 2080, which comes with core clock speeds of 1515 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 2944 SPUs along with 184 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
GeForce RTX 2080		215 Watts
	Difference: 95 Watts (79%)

Memory Bandwidth

In theory, the GeForce RTX 2080 should perform much faster than the GeForce GTX 1660 Ti in general. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 163840 (56%)

Texel Rate

The GeForce RTX 2080 should be quite a bit (approximately 94%) faster with regards to texture filtering than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 134760 (94%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 is the winner, by a large margin. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 24960 (35%)

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 largest amount of information (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video 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 maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
