GeForce GTX 1660 Ti vs GeForce GTX 980 Ti

Intro

The GeForce GTX 1660 Ti makes use of a 12 nm design. nVidia has clocked the core speed at 1500 MHz. The GDDR6 memory is set to run at a frequency of 12000 MHz on this particular model. It features 1536 SPUs as well as 96 TAUs and 48 ROPs.

Compare all of that to the GeForce GTX 980 Ti, which features a GPU core clock speed of 1000 MHz, and 6144 MB of GDDR5 RAM set to run at 1750 MHz through a 384-bit bus. It also features 2816 SPUs, 176 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti 120 Watts
GeForce GTX 980 Ti 250 Watts
Difference: 130 Watts (108%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 980 Ti should in theory be a small bit superior to the GeForce GTX 1660 Ti overall. (explain)

GeForce GTX 980 Ti 336000 MB/sec
GeForce GTX 1660 Ti 294912 MB/sec
Difference: 41088 (14%)

Texel Rate

The GeForce GTX 980 Ti will be a lot (approximately 22%) faster with regards to anisotropic filtering 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

If using a high screen resolution is important to you, then the GeForce GTX 980 Ti is the winner, and very much so. (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 maximum amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
