VS

GeForce RTX 2080 SUPER vs Geforce GTX 1080 Ti

Intro

The GeForce RTX 2080 SUPER comes with a GPU core clock speed of 1650 MHz, and the 8192 MB of GDDR6 RAM is set to run at 1937 MHz through a 256-bit bus. It also is made up of 3072 SPUs, 192 TAUs, and 64 Raster Operation Units.

Compare those specs to the Geforce GTX 1080 Ti, which has a clock frequency of 1480 MHz and a GDDR5X memory frequency of 1376 MHz. It also makes use of a 352-bit bus, and makes use of a 16 nm design. It features 3584 SPUs, 224 Texture Address Units, and 88 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the GeForce RTX 2080 SUPER should perform a bit faster 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 will be a bit (approximately 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

If running with high levels of AA is important to you, then the Geforce GTX 1080 Ti is a better choice, and very much so. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 fill rate is also dependant 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 max fill rate.
