GeForce GTX 1660 Ti vs GeForce RTX 2080

Intro

The GeForce GTX 1660 Ti comes with clock speeds of 1500 MHz on the GPU, and 12000 MHz on the 6144 MB of GDDR6 memory. It features 1536 SPUs along with 96 Texture Address Units and 48 Rasterization Operator Units.

Compare all of that to the GeForce RTX 2080, which comes with GPU core speed of 1515 MHz, and 8192 MB of GDDR6 memory running at 14 MHz through a 256-bit bus. It also features 2944 SPUs, 184 Texture Address Units, and 64 Raster Operation Units.

Theoretically speaking, the GeForce RTX 2080 is 56% quicker than the GeForce GTX 1660 Ti overall, due to its higher data rate. (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 (more or less 94%) faster with regards to AF 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

The GeForce RTX 2080 should be a lot (more or less 35%) better at full screen anti-aliasing than the GeForce GTX 1660 Ti, and should be capable of handling higher screen resolutions more effectively. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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