GeForce RTX 3080 Ti vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1717 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this model. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

Radeon RX 5500 XT		229376 MB/sec
	Difference: 704921 (307%)

Texel Rate

The GeForce RTX 3080 Ti will be much (approximately 189%) more effective at texture filtering than the Radeon RX 5500 XT. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 285704 (189%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is superior to the Radeon RX 5500 XT, and very much so. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 97936 (178%)

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 megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
