GeForce GTX 1660 Ti vs GeForce RTX 2080 Ti

Intro

The GeForce GTX 1660 Ti has core speeds of 1500 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 RAM. It features 1536 SPUs along with 96 Texture Address Units and 48 ROPs.

Compare those specs to the GeForce RTX 2080 Ti, which features a GPU core clock speed of 1350 MHz, and 11264 MB of GDDR6 memory set to run at 1750 MHz through a 352-bit bus. It also is comprised of 4352 SPUs, 272 Texture Address Units, and 88 ROPs.

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

Texel Rate

The GeForce RTX 2080 Ti should be a lot (approximately 155%) faster with regards to anisotropic filtering 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%) more effective at full screen anti-aliasing than the GeForce GTX 1660 Ti, and also should be capable of handling higher screen 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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
