GeForce GTX 1080 vs GeForce RTX 2070 Super

Intro

Compare all of that to the GeForce RTX 2070 Super, which comes with a GPU core clock speed of 1605 MHz, and 8192 MB of GDDR6 RAM set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

GeForce GTX 1080		327680 MB/sec
	Difference: 131072 (40%)

Texel Rate

The GeForce GTX 1080 should be a little bit (more or less 0%) better at texture filtering than the GeForce RTX 2070 Super. (explain)

GeForce GTX 1080		257120 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 320 (0%)

Pixel Rate

The GeForce GTX 1080 is a little bit (approximately 0%) better at AA than the GeForce RTX 2070 Super, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1080		102848 Mpixels/sec
GeForce RTX 2070 Super		102720 Mpixels/sec
	Difference: 128 (0%)

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 past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
