GeForce RTX 2080 SUPER vs Geforce GTX 1080 Ti

Intro

The GeForce RTX 2080 SUPER uses a 12 nm design. nVidia has set the core frequency at 1650 MHz. The GDDR6 RAM runs at a frequency of 15500 MHz on this card. It features 3072 SPUs as well as 192 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Geforce GTX 1080 Ti, which comes with core clock speeds of 1480 MHz on the GPU, and 1376 MHz on the 11264 MB of GDDR5X memory. It features 3584 SPUs along with 224 Texture Address Units and 88 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the GeForce RTX 2080 SUPER should in theory be a small bit better than the Geforce GTX 1080 Ti overall. (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 a little bit (more or less 5%) faster with regards to 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 will be a lot (about 23%) faster with regards to AA than the GeForce RTX 2080 SUPER, and will be able to handle higher resolutions without losing too much performance. (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.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, 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 that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
