	Difference: 131072 (40%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition will be just a bit (more or less 5%) faster with regards to texture filtering than the GeForce GTX 1080. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
GeForce GTX 1080		257120 Mtexels/sec
	Difference: 11680 (5%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition will be a small bit (about 5%) better at AA than the GeForce GTX 1080, and also able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
GeForce GTX 1080		102848 Mpixels/sec
	Difference: 4672 (5%)

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 largest amount of information (counted in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high 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 number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per 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. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of 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.
