GeForce GTX 1080		327680 MB/sec
	Difference: 114688 (35%)

Texel Rate

The Radeon RX 6750 XT is quite a bit (about 34%) better at anisotropic filtering than the GeForce GTX 1080. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
GeForce GTX 1080		257120 Mtexels/sec
	Difference: 86880 (34%)

Pixel Rate

The Radeon RX 6750 XT will be much (about 34%) more effective at full screen anti-aliasing than the GeForce GTX 1080, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
GeForce GTX 1080		102848 Mpixels/sec
	Difference: 34752 (34%)

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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
