Geforce GTX 1080 Ti vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which comes with GPU clock speed of 1670 MHz, and 4096 MB of GDDR6 memory running at 1750 MHz through a 128-bit bus. It also is comprised of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Radeon RX 5500		229376 MB/sec
	Difference: 266240 (116%)

Texel Rate

The Geforce GTX 1080 Ti should be a lot (more or less 126%) better at texture filtering than the Radeon RX 5500. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 184560 (126%)

Pixel Rate

The Geforce GTX 1080 Ti will be much (more or less 144%) faster with regards to AA than the Radeon RX 5500, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 76800 (144%)

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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out 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 card will be at handling 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 that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
