Texel Rate

The Radeon RX 6800 will be much (approximately 59%) better at AF than the GeForce GTX 1080. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce GTX 1080		257120 Mtexels/sec
	Difference: 150880 (59%)

Pixel Rate

The Radeon RX 6800 is a lot (about 59%) faster with regards to full screen anti-aliasing than the GeForce GTX 1080, and will be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce GTX 1080		102848 Mpixels/sec
	Difference: 60352 (59%)

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 (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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