GeForce RTX 2080 SUPER vs Geforce GTX 1080 Ti

Intro

Compare all that to the Geforce GTX 1080 Ti, which features core clock speeds of 1480 MHz on the GPU, and 1376 MHz on the 11264 MB of GDDR5X RAM. 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

The GeForce RTX 2080 SUPER should theoretically perform 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 should be a little bit (about 5%) better 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

The Geforce GTX 1080 Ti should be quite a bit (about 23%) more effective at anti-aliasing than the GeForce RTX 2080 SUPER, and also will be able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, 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 maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
