GeForce RTX 2080 Ti vs Radeon RX 5500 XT

Intro

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

Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 216104 (143%)

Pixel Rate

The GeForce RTX 2080 Ti will be much (more or less 116%) faster with regards to FSAA than the Radeon RX 5500 XT, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 63856 (116%)

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 (in units of MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 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 are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the 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 that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
