GeForce RTX 2080 SUPER vs Geforce GTX 1080 Ti

Intro

Compare those specifications to the Geforce GTX 1080 Ti, which makes use of a 16 nm design. nVidia has clocked the core frequency at 1480 MHz. The GDDR5X RAM runs at a frequency of 1376 MHz on this particular card. It features 3584 SPUs along with 224 TAUs and 88 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER will be 2% quicker than the Geforce GTX 1080 Ti overall, due to its higher data rate. (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 will be a little bit (approximately 5%) more effective at texture filtering 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 using lots of anti-aliasing is important to you, then the Geforce GTX 1080 Ti is the winner, by far. (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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
