Geforce GTX 1080 Ti vs Radeon RX 5500 XT

Intro

Compare that to the Radeon RX 5500 XT, which comes with GPU core speed of 1717 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 128-bit bus. It also features 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Geforce GTX 1080 Ti		250 Watts
	Difference: 120 Watts (92%)

Memory Bandwidth

In theory, the Geforce GTX 1080 Ti is 116% faster than the Radeon RX 5500 XT overall, because of its higher bandwidth. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 266240 (116%)

Texel Rate

The Geforce GTX 1080 Ti is quite a bit (more or less 119%) more effective at AF than the Radeon RX 5500 XT. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 180424 (119%)

Pixel Rate

The Geforce GTX 1080 Ti will be quite a bit (more or less 137%) more effective at AA than the Radeon RX 5500 XT, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 75296 (137%)

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 across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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