Geforce GTX 1080 Ti vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which has a GPU core clock speed of 1605 MHz, and 8096 MB of GDDR6 RAM running at 1750 MHz through a 256-bit bus. It also features 2560 Stream Processors, 160 TAUs, and 64 ROPs.

Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 74720 (29%)

Pixel Rate

The Geforce GTX 1080 Ti will be much (about 27%) more effective at FSAA than the Radeon RX 5700 XT, and will be capable of handling higher resolutions better. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 27520 (27%)

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 data (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
