GeForce RTX 2080 SUPER vs Geforce GTX 1080 Ti

Intro

Compare all that to the Geforce GTX 1080 Ti, which comes with GPU clock speed of 1480 MHz, and 11264 MB of GDDR5X RAM running at 1376 MHz through a 352-bit bus. It also features 3584 Stream Processors, 224 Texture Address Units, and 88 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER should be a little bit faster than the Geforce GTX 1080 Ti in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Geforce GTX 1080 Ti		495616 MB/sec
	Difference: 12288 (2%)

Texel Rate

The Geforce GTX 1080 Ti is just a bit (approximately 5%) more effective at AF than the GeForce RTX 2080 SUPER. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 14720 (5%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 1080 Ti is a better choice, by a large margin. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 24640 (23%)

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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
