GeForce GTX 1660 Ti vs GeForce GTX 980 Ti

Intro

Compare all of that to the GeForce GTX 980 Ti, which uses a 28 nm design. nVidia has set the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this card. It features 2816 SPUs along with 176 TAUs and 96 Rasterization Operator 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

The GeForce GTX 980 Ti, in theory, should be a bit faster than 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 should be quite a bit (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 running with lots of anti-aliasing is important to you, then the GeForce GTX 980 Ti is the winner, by far. (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 max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels that the graphics chip can 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
