GeForce GTX 1080 vs GeForce RTX 2080 SUPER

Intro

Compare those specifications to the GeForce RTX 2080 SUPER, which makes use of a 12 nm design. nVidia has set the core speed at 1650 MHz. The GDDR6 RAM is set to run at a frequency of 1937 MHz on this specific model. It features 3072 SPUs as well as 192 Texture Address Units and 64 ROPs.

GeForce GTX 1080		327680 MB/sec
	Difference: 180224 (55%)

Texel Rate

The GeForce RTX 2080 SUPER will be much (about 23%) more effective at AF than the GeForce GTX 1080. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 1080		257120 Mtexels/sec
	Difference: 59680 (23%)

Pixel Rate

The GeForce RTX 2080 SUPER should be just a bit (about 3%) faster with regards to AA than the GeForce GTX 1080, and will be capable of handling higher screen resolutions better. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 1080		102848 Mpixels/sec
	Difference: 2752 (3%)

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 max amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
