GeForce GTX 1660 Ti vs GeForce GTX 980 Ti

Intro

Compare those specs to the GeForce GTX 980 Ti, which comes with GPU core speed of 1000 MHz, and 6144 MB of GDDR5 RAM set to run at 1750 MHz through a 384-bit bus. It also is comprised of 2816 Stream Processors, 176 Texture Address Units, and 96 Raster Operation Units.

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

Texel Rate

The GeForce GTX 980 Ti should be much (about 22%) better at 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 lots of anti-aliasing is important to you, then the GeForce GTX 980 Ti is superior to the GeForce GTX 1660 Ti, 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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
