GeForce GTX 1660 Ti vs GeForce GTX 980 Ti

Intro

The GeForce GTX 1660 Ti comes with a core clock frequency of 1500 MHz and a GDDR6 memory frequency of 1500 MHz. It also uses a 192-bit memory bus, and uses a 12 nm design. It is made up of 1536 SPUs, 96 Texture Address Units, and 48 Raster Operation Units.

Compare those specifications to the GeForce GTX 980 Ti, which features a clock frequency of 1000 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 384-bit memory bus, and uses a 28 nm design. It is made up of 2816 SPUs, 176 TAUs, and 96 Raster Operation Units.

The GeForce GTX 980 Ti should be a lot (about 22%) more effective at AF than the GeForce GTX 1660 Ti. (explain)

GeForce GTX 980 Ti 176000 Mtexels/sec
GeForce GTX 1660 Ti 144000 Mtexels/sec
Difference: 32000 (22%)

Pixel Rate

The GeForce GTX 980 Ti will be a lot (more or less 33%) better at full screen anti-aliasing than the GeForce GTX 1660 Ti, and also will be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 980 Ti 96000 Mpixels/sec
GeForce GTX 1660 Ti 72000 Mpixels/sec
Difference: 24000 (33%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
